changed and the hotshot invocation wasn't changed along.  Untested.

Add a send_call() method that computes a new msgid and hands the
message off to the smac layer.  Uses __msgid_lock()

call() still uses __call_lock, but callAsync() does not.  callAsync()
does not use any lock beyond what send_call() does.

each time round the loop (with a 30 sec. timeout).

should fix the problem that messages from different processes or
threads could be intermingled.  The code was rewritten to build up the
lines of the error message in a list which is joined by "\n"
characters at the end.

values that connect_ex() may return when we're connected).  This seems
to resolve the last hangs observed on Win2K.  There are still
(unrelated) hangs on Win98 though.

read-write connection is not available.  This refactors
ClientStorage.notifyConnected() into two functions, testConnection()
and notifyConnected().  testConnection creates the RPC stub and calls
the register() method; it returns the stub plus a flag indicating
whether this connection was preferred or sub-optimal.  If the
register() method raises ReadOnlyError, and the new option
read_only_fallback was true on the ClientStorage constructor, it is
retried with its read_only argument set to 1, and the stub is returned
with the sub-optimal flag.  notifyConnected() now receives the stub
returned by testConnection(), and starts the verification as before.

XXX The read_only_fallback  feature is not yet tested.

XXX More work is needed; when a suboptimal connection is used, the
ConnectThread must stay around trying to get a preferred connection,
and then it must switch connections on the ClientStorage (how???).

different classes that both define a register() method, with different
signatures.  Rename StorageServer.register() to
register_connection().  Also rename its newConnection() method to
new_connection(), for naming consistency.

more understandable.

Got rid of the Connected() exception -- connect(), now renamed to
try_connect(), returns a 1/0 result instead of raising Connected() to
indicate success.

Also, simplify the test for exceptions received by the client.  If the
class is a subclass of Exception, there's no need to ask if the
instance is of type ClassType.

Increase the timeout from 10 to 30 seconds and add a message to the
failIf() call.

lock.  The lock is now never held for a long time, only while
self.thread is being assigned or inspected, and while a thread is
being created, started or stopped.  Waiting for an event or joining a
thread is now done without holding the lock.  There is no longer a
fear of AttributeError.

When a thread join doesn't succeed within 30 seconds, a message is
logged, and depending on the situation, the join is retried.

The old code would avoid hosing the system when the first jar failed
during its finish.  The logic is that the failure means that
transaction did not commit, so it was safe for all the other jars to
abort.  There are counter-examples to this assumption.  For example,
ZEO could fail after commiting the transaction on the server but
before communicating that success to the client.  It would lead to
inconsistency if the other jars aborted after the first committed.

The solution is to reduce the special case yet further:  If a
single-jar transaction fails during the finish, assume the transaction
is aborted and avoid hosage.  If the jar actually committed, it's
possible to get back to a consistent state since only one jar was
involved.

The effect of this change will be to cause transactions to fail
immediately, rather than the first time they call store() or
abortVersion() or some other write-method.  Since the Connection now
treats empty transactions as a special case, this change will not
change the class of transactions that fail.
