[Pianod] wsgw hanging on RasPi; deadlock?

[Perette Barella]

By completion flags, were you thinking like a bool that either thread could set and the main could watch?  That would require the main thread to keep running and monitoring, whereas with the mutex solution, main doesn't have to spin.  If this wasn't what you were thinking, I'd be curious for details of your idea.  I'm new to pthreads too, so you may be onto something I don't know about.
