This is just one of the fields which needs development in Customdrawn, 
at least for some backends, like X11. Momentarily I've simply taken 
advantage of X11 message queue, but I'm also considering other 
possibilities, such as using Glib's GLoop, or implement one using fpc 
TThreads, just to mention two possible candidates. It would be 
preferable to have an event queue common for all backends, and therefore 
this implies taking into account many factors.
However, it that's what you need, I think you'll get it. Sooner or later :-)
