Re: thread-safe mmap module ?

Based on other comments, you may not really need process-shared memory, but if you still do, you might check IPC::Mmap. It was developed in part to assist in creating a threads-friendly Perl debugger, so it should be thread safe.

(Hmm, looks like the docs have gotten lost in CPAN's new restriction on package content, you'll have to scroll back to older versions to read the docs)
