It's due to competition between the Squeak event loop, which uses Xlib,
and the wxWidgets event loop, which uses GTK. I haven't resolved this
entirely yet, but my current version feels much faster. I don't think
the extra indirection should have any noticeable effect for most
situations -- once the events get through, rendering is very fast.
