One of the problems we're having, and why an embedded interpreter is 
much faster, is that the Foundation and AppKit frameworks get dynamicly 
loaded. This means preloading doesn't work, which in turn means much 
slower loading. If anyone knows how to make sure preloading works with 
Python modules please tell us, that would be really helpfull.

Jack has experimented with a /usr/local/bin/python that has been linked 
with AppKit and that caused much faster loading of PyObjC. This won't 
make it into the 2.3 release because it is unclear what the side 
effects of linking with AppKit are. We want to be 100% sure that 
/usr/local/bin/python runs without access to the WindowServer.
