timoOutLoopStartLab() checks if any transactions have been delayed
for so long that we are forced to perform some action (e.g. abort,
resend etc).

It is *MEANT* to (according to the comment):

The comment (as all do) lies.

the API connect reference is not very random, producing incredibly
predictable "random" numbers. This could lead to both txns being
aborted instead of just one.

Before:
timeout value: 123 3
timeout value: 122 2
timeout value: 122 2
timeout value: 122 2

After:
timeout value: 127 7
timeout value: 126 6
timeout value: 129 9
timeout value: 139 19
timeout value: 137 17
timeout value: 151 31
timeout value: 130 10
timeout value: 132 12

If ::exteral_lock hadn't been called, we'd have no NDB object,
so need to check/get one here.

It looks like sql_show.cc is the only place that does this....
or at least the other places will be well hidden.
