Calling g_main_loop_quit from another thread

[Braden McDaniel <braden endoframe com>]

Is it safe to call g_main_loop_quit from another thread?

I have a GMainLoop that is watching a GIOChannel for input in a thread.
I am trying to end this thread by calling g_main_loop_quit from a
different thread. But when I do this, the thread running the GMainLoop
deadlocks in a call to poll from g_main_context_check.

My workaround for the moment has been to add an idle callback that
checks a boolean flag to the thread running the GMainLoop and call
g_main_loop_quit in the callback function. Though this is rather
annoying; particularly considering calling gtk_main_quit from another
thread seems to work fine.

Is there some way to get the call to g_main_loop_quit from another
thread to work?
