You are absolutely right; mutexes /are/ useless from signal

How about GAsyncQueue's? They're supposed to be thread safe without the need
of locking... How about within a single thread?
Add a unix signal number in the signal handler, and suck it out again in a
custom event source's prepare method. The prepare method can return -1 for its
timeout contribution, and true/false if there's something in the queue.
So... poll *will* exit because of the signal... but will it check its
event sources and
everything... if no file descriptor is ready and timeout isnt reached ?
you'll have to
test it out with an idle main loop... because for the same reasons...
you cant call
g_main_context_wakeup().
