Yes.  GC operations can happen
in a non-GUI thread.

Only one thread is allowed in X windows.   
Graphics operations can happen in every
thread and therefore need to be synchronized with the UI thread.  

On Windows, GDI allows more than one
thread so no lock is necessary. 

Thanks for the answer Steve.
I don't understand which graphics operation can happen in other threads?
E.g. a Table redraw() calls checkWidget that ensures the UI Thread.
Or do you mean the user could use a GC object from another thread?
