You could give each thread it's own interpreter and keep that
interpreter around from one request to the next. Or share a pool of
interpreters to conserve memory.
There's a lot of work going in to this threading model
(interpreter-per-thread, or ithreads) right now by a fellow named Artur
Bergman (search the perl5-porters archives[1] for "Artur" or "ithreads"
to get a handle on it). They're currently tackling the regexp piece.
ithreads was added by the fork() emulation ActiveState added for Win32
platforms, I think.
The real draw for this ithreads stuff, IMHO, is the nascent mod_perl 2.0
and it's support for Apache 2.0's multithreaded configurations.
