FTR, I could reproduce on the Mac, though still irregularly.

This was the problem and I was able to work around it pretty easily  
and added a rough test that reproduced all the time here (though is  
still subject to timing issues, it may give a false positive without  
the fix but always passes with the fix). I filed a bug in Plexus for  
the actual issue.
