As halley stated, mod_perl does provide shared memory for modules loaded in the startup.pl. The way this works is that it's loaded and all the children get to share it. If they write to the shared memory, the shared space gets copied to that child, so it's a Copy-On-Write strategy. This also means that changes made by one child do not get propagated to other children.
My criteria for good software:
  1. Does it work?
  2. Can someone else come in, make a change, and be reasonably certain no bugs were introduced?
