I seriously think that the code triggering the warning should be backed off,
I discussed about the warning/global speedup issue with Guido at 
Europython, I didn't propose there to back it off, and we didn't finish, 
still it was more or less clear that there is no strong case at the moment 
for the warning, because it is unclear whether is the right kind of flavor 
of limitation in terms of having a simple explanation for it, the issue 
with __init__ modules is still unclear etc...
