[Valgrind-developers] pth_cvsimple

[Nicholas N. <n.n...@gm...>]

I'm getting reasonable often failures in none/tests/pth_cvsimple.c.
It has a comment:

  // Nb: it's not certain that we'll hit here.  It's possible that the two
  // inc_count threads could fully run before watch_count begins, and so
  // pthread_cond_wait() is never called.  Or, we could get a spurious
  // wake-up in watch_count().  Nonetheless, it's very likely that things
  // will work out as expected, since we're starting watch_count() first.
  if (condvar_was_hit == 1)
    printf("condvar was hit!\n");
  else if (condvar_was_hit > 1)
    printf("condvar was multi-hit...\n");
  else
    printf("condvar was missed...\n");

Any suggestions on how to improve this unreliability?  Could a sleep()
call be inserted?  Should the output string not depend on the
condvars?
