I think so, but I'm not sure.

This might be relevant.  My test suite failures occur on a loaded
machine, because the test case runner parallelises separate tests.

Does this produce a particular message, when it occurs ?

There are other possible approaches to this situation than to hope to
win the race.  But I hesitate to suggest adding additional code to
this area, having seen what's there already...

If you would like to suggest a debug printf, or name lines of source
code, I can probably arrange to see if this is happening.
