with a 99.872% confidence level, i can confirm your belief.

if you don't understand the answer to this already, it suggests that it
may be unwise for you to be using threads at all.

the use of threads in GUI toolkits that originated in the X Window world
is generally quite difference than the use of it with GUI toolkits that
originated in the win32 world. in particular, the general rule in GTK
is:

  EITHER make GTK/GDK/X11 calls from a single thread only OR
  use GDK_THREADS_{ENTER,LEAVE} around every (group of) GTK/GDK/X11
  call(s).

googling will turn up plenty of refs to this stuff.

in general, its not a problem. there are some specific instances where
it can be an issue.
