For the mod_perl crash with Event that I posted at the URL below, I would suspect that there's some affinity with the original worker thread.  Can anyone in mod_perl land confirm?

I'm also aware of a third-party diagnostic module that could use a hint, and in general I wonder if anyone knows of specific interface requirements that would need to be provided by a new hook for indicating when a connection or request leaves the original thread or is handled by a new one.
