I have applied a modified version of Duncan Grisby's threading patch to
CVS (it is modified so that it does not affect non threaded copies of
python). You could try checking it out of CVS, or if you don't want to go
to the trouble of CVS and patching automake, get a nightly snapshot of
gnome-python from ftp.jimpick.com and copy gtkmodule.c and gtk.py to the
build directory. It should have an "#ifdef WITH_THREAD" close to the top
if it is the correct version.
With that one, you should be able to thread the application (unless I made
some mistakes altering Duncan's patch), and when you want to call GTK
routines from another thread (ie. not from a signal handler or other
callback), call threads_enter() before and threads_leave() after.
If no one sees any bugs in this code, I will release it soon.
James Henstridge.
