I think having all those extra registers around, and the fact that most 
of the operations take a destination and two operands instead of just 
dest and src, might make it a bit nicer.  But then again, the fact that 
Psyco was designed for x86 might mean that it would be hard to take 
advantage of.  I really don't know, it's been a while since I've looked 
at the source.

I know that it's a real bitch to compile on OS X (but I did).. it's 
very odd.  It must work to some degree because Pyste uses it, but I 
haven't taken a serious look at the output.  It seems like one of those 
XML formats where you need to write a pretty significant translator 
from it to a data structure worth using.
