I think it's *far* more likely that there is a bug in the application
you are using to test with.

It's quite possible for a threaded application to open a GL context in
one thread and do OpenGL calls in another thread.  It's easy to imagine
a situation where there would be a race hazard that would result in some
thread implementations allowing the application to work as intended and
other thread implementations to show up the problem that was there in the
application all along.

Turning off the glIsValidContext() would give such broken applications
more time to sort out their problems so the race condition would be much
less aparrent than it would otherwise be.

I very much doubt that the thread library and/or OpenGL and/or PLIB is
to blame in this case...although it's obviously possible.
