Maneesh,
Can you show me the full backtrace of all threads when it deadlocks? I just
realized that xg_select is called from wait_reading_process_output, which I
believe means it's callable from multiple threads at once.
The behavior of g_main_context_acquire is *documented* to never block, but
rather to return FALSE if another thread has the context; if the behavior has
been changed to block on OS X -- and the thread with the context is calling
pselect() and waiting to return -- this would match your experience.
John
