I've tried to test using pystone, but am seeing more differences between
runs than there is between python w/ the patch and w/o when there is no
hook installed. The highest pystone is actually from the binary w/ the
patch, which I don't really believe unless it's some low level code
generation affect. The cost is one test of a global variable and then a
switch to the branch that doesn't call the hooks.
I'd be happy to try to come up with better numbers next week after I get
home from pycon.
