File::Map mmap()s a file and makes it visible as a perl string. You can modify
it for example by using the lvalue form of substr().

MMapDB uses File::Map and provides some kind of a hash. (I have just uploaded
version 0.07 that handles utf8 strings correctly (me thinks so))

There is a mod_slotmem.c floating around. It provides something like apache's
scoreboard. That means each worker gets its own piece of shared memory to
write to while all slots can be read by anyone. I think it can be interfaced
to be used by Perl.
