Shared mem is an option, but a nonportable option. Moreover, file access is 
intelligently cached on today's Unices, so file access (using mmap() on 
systems that have it) is as good. In fact, some selfmade benchmarking of 
mmap() and sysv-shmem showed that sysv-shmem is a lot slower on linux. I'd 
look on CPAN for some existing module in this direction, I bet there is one.
