[Pythonmac-SIG] Re: MacPython 2.2.2 final candidate

[Alexandre Parenteau]

Hi Jack,

I cannot be sure for OS9 since I'm not a regular user. To your request I
booted OS9 and started the interpreter : it looks fine, faster too
(although it is less sensible compared to OSX speed up), and I believe
the yielding is still honorable (I can switch application, do other
things, while running autotest).

A regular OS9 user should be able to tell more.

Alexandre,
have you tried this on older, slower (OS9?) machines too? If it 
works reasonably there as well I'll just drop this in (albeit 
for MacPython 2.2.3, 2.2.2 is finished).
Otherwise the fix would become more cumbersome: I think we would 
have to use 1 on OSX and 6 on OS9 or somesuch.
