there is absolutely no problem mixing pthreads, C++, GTK+ and
gtkmm. you need to understand multithreaded programming, which is not
trivial, and it is best if you stick to the model that only one thread
ever calls gtkmm/GTK+/GDK/Xlib functions. the latest gtkmm has a nice
class (called Dispatcher, i forget which namespace) that makes this
rather easy to do.

but i repeat: there are no problems doing this (i've been doing it for years).
