There aren't many optimizations yet that would be useful 
on other platforms. The optimizations made after the 1.0 
release were aimed to minimize the performance hit incurred 
when converting static writable data to data allocated from 
the heap and accessed via Thread Local Storage. It's 
encouraging to see that it was successful, since the 
performance of the Series 60 version seems to equal that of 
the 770 version at least in Pystone. Has anyone tried to 
measure how many Pystones the 770 gets with Python 2.2? 
That result would be directly comparable.

Imports are still hideously slow, though. With the 1.1.6fast 
build, it takes 2.34 seconds to "import urllib" on a 6630. 
This is something we'll probably look into in the 
near future.
