I'm replying to myself again; I need to get out more!

I modified Scott's test program to get pfloat object to break. The 
modified program is:

import psyco
psyco.full()

from math import pow

#~ def foo(etasize):
    #~ pow (1.0, etasize)
def foo(etasize):
    return 5.0 + etasize
foo ("1")


I've gone ahead and submitted a bug report as well as a patch that 
appears to fix this to sourceforge.
