No, individual re objects should be.  The MatchObject you get back
from a matching operation contains references to the string, groups,
and original regex object, but a RegexObject shouldn't ever change
after it's been created.  Tim Peters put some effort into making the
cache thread-safe.  Brian, can you post the relevant bits of code so
we can see what's going on?

Surprisingly enough, Python has taught me more about Lisp than Lisp ever did.
