pthreads have been flakey for me for a while, it was just the recent
changes that made the flakeyness occur more regularly. The two tests
that give me irregular breakage are GCTest & WaitTest. WaitTest uses
ocasionally to either hang in the second thread for more than 300sec, or
to quit the second thread with a bad value. GCTest ocassionally seems to
miss a line of output. I've noticed the frequency of flakey output
increased after my change from

(jthread_on_current_stack): De-inlined to fix compiler
(jthread_on_current_stack): Moved over here.
but I'd be surprised if deinlining it skewed the calculations as they
use stackMin/Max which are set when a thread is created.
