GTK peers

[John Leuner]

I committed some changes to the GTK native peer code to try get it to
run a little further than it did before.

Now I can sometimes get a very simple application (with one Frame) to
run some of the time.

It seems that sometimes there is some threading problem which causes an
Xlib error:

Xlib: unexpected async reply (sequence 0x29)!

Using kissme, if I enable some internal debugging (with -t jni), this is
less likely to happen, so I think it's a thread timing issue.
