Not exactly.  Idle callbacks are always invoked on the main loop thread, even if queued from another thread, 
so you can use this to ensure that ui work happens only on the mainloop's thread.

Alternatively, you can do ui stuff from a worker thread if you grab the gdk lock, first.

In perl, this gets tricky because of the way scalars may or may not be shared between threads.  What you can 
do depends on how you have set up your stuff.
