Should I do that within *all* such functions even if I'm not using
threading? The 25-April-1999 note in NEWS says that
threads_enter()/threads_leave is *not* required from timeout/idle
functions. I figured that wrapping was needed when calling gtk
functions from threads other than the one that called mainloop().
OTOH, I certainly found PyGtk_BlockThreads()/PyGtk_UnblockThreads()
essential within my *C* signal handlers when calling back to python
even though I wasn't using threads.
Maybe there should be a little note in the distribution outlining
these requirements.
