I'm not sure if this is the right forum at this point for these issues. I've been lurking on the list for a while now and don't remember any traffic directed at these issues.
With NPTL the threading model changes. It's mostly a Linux 2.6 issue. What if any changes are needed to make Python stable in a NPTL environment and what changes might we want to take advantage of the improved performace and new features.
Along the same lines, some kernels now support CPU affinity. It's a low level scheduling issue, but necessary to avoid with certainty problems with the GIL. Do we want to expose some of the controls in Python? How do these controls interact with processes and threads?
