Running the standard test suite on 10.6 and seeing no regressions 
compared to the same suite on 10.5.x seems a reasonable necessary 
requirement.  We have the resources to do that.  Beyond that, as Ronald 
suggests, I think it important to go through the open issues in the next 
couple of days and identify and flag any potential release-blockers 
(besides the IDLE problem already mentioned).

One other open issue is 64-bit support in the python.org OS X installer.  
There have been discussions and requests in the past and, with Apple 
providing 64-bit out of the box in 10.6, it seems like it's time to 
provide something on python.org as well.   One option: continue to 
provide a 32-bit only installer for ppc and i386 for 10.3.9 and beyond 
and add a second installer image with 3-way (ppc, i386, x86_64 but no 
ppc64) 32/64 for 10.5 and beyond.   Ronald, is that your current
