gdk_threads_leave in gtk callback ?

[Vladimir <kv11111 mail ru>]

Hello,

I'm writing program with several threads each of which uses gtk.
I need to wait for one of the threads in gtk-generated callback. I can't do
it directly because of gdk lock. So the question is: can I temporarily
release gdk lock in gtk-generated callback ? Will it cause any problems ?
