Cool, no apparent bugs under Snow Leopard. I did notice that
the menus still disappear when a dialogue windows pops up.
I think that this bug was present before though.

We will need a valgrind expert for that.

Talking performance, we do have to solve the display interrupt issue though.
Can we recursively handle events during the repaint phase.
In that case, I can probably do something. Otherwise, I will need ideas.

I still have some problems with the keyboard from time to time.
At a certain point C-x prompts me for a Scheme command,
when I wanted to do C-x C-c. After a fresh restart, C-x C-c worked fine...
