They are allocated on the stack and can be initialized at compile time.
there is also a little blurb here [1] about some technical details 
about not having to call g_thread_init() from a program or library
that might or might not be included in a threaded program.

A GMutex is allocated on the heap, so it doesnt need to be a global
or static variable.

your glib/gtk+, so since I'm still idly typing here this
