The test code used to do this:

for _, tc := range tests {
	ch <- &tc
}

Note that &tc is always the same value here.  As the value is
received from the channel, the sender can loop around and
change the contents of tc.  This means that the receiver's
value is unstable and can change while it is in use.

Close of closed channel panics.

There were duplicate closes and missing closes,
with the result that the program was rarely testing
as much as it seemed to be.  Now it finishes.

Re-implement the debugging helper to be independent of the existing
implementation.  This is preparatory to a rewrite to clean up issue 1416.

	This was broken after the last update (2011-01-20).
	However, I'm not sure if the changed example is a
	sensible use of import(), so I'd appreciate comments.

The functionality we want (shared ppid) is implied
by CLONE_THREAD already, and CLONE_PARENT
causes problems if the Go program is pid 1 (init).

The o+i*p approach to visiting select cases in random
order stops being fair when there is some case that
is never ready.  If that happens, then the case that follows
it in the order gets more chances than the others.

In general the only way to ensure fairness is to make
all permutations equally likely.  I've done that by computing
one explicitly.

Makes the permutations correct for n >= 4 where
previously they were broken.  For n > 12, there's not
enough randomness to do a perfect job but this should
still be much better than before.

Fixes #1425.

The default float type is not very useful but for the most basic applications.
For instance, as it is now, using the math package requires conversions for float
variables (the arguments for math functions are usually float64). Typical real
applications tend to specify the floating point precision required.

This proposal removes the predeclared types float and complex. Variable declarations
without type specification but with constant floating point or complex initializer
expressions will assume the type float64 or complex128 respectively.

The predeclared function cmplx is renamed to complex.
