I had no problems using IPC::Sharable with mp2 and it may be what
you're looking for.  I do not use this in production as the data shared
does not persist user permissions, e.g., a shared object create by root
can be accessed by any process running under any user permitting they
have the 4-character key.

Yes, understand your Apache MPM, how Perl is compiled, and the
implications of using shared memory (/shm) in general.  I wouldn't take
this lightly in the context of a production web server.
