Good question. In Perl, this is difficult since the Threads.pm muteces are exactly what's holding PerlThreads back in the stone age. I'm working on a fake mutex that uses flock on some file. Read more about the difficulties with flock here. In the meantime, just flock the library or some arbitrary file everytime you wish to access the file. Keep in mind that this defeats any use of threads within that library- only one thread at a time may access it and your thread stacks may expand greatly. I'll keep you posted on my own efforts as well. Good luck!
