in thread Sharing data structures among http processes?

Having trying myself to implement a semaphore-based locking mechanism for IPC SysV shared memory, I'd recommend IPC::ShareLite for general purposes. It comes with a powerful locking mechanism, which is incredibly similar to flock() !
Apache::SharedMem also depends on this module.

[Corion]: hippo: Yes, but I'm not sure that it's even worth the effort of implementing it at all...
[Corion]: You'll only ever need that option if you have a long-running query whose results are not cached by your DB already, and in those cases I presume that the programmer will want to maintain the temporary tables themselves - I wouldn't know when to drop ...
[Corion]: ... the temporary tables, and also don't have a good idea on how to create unique table names for them
[hippo]: OIC. In that case leave it out but invite feature requests and see if any of the users suggest it. :-)
[Corion]: Talking about this makes me realize that it's likely only a half useful idea. But it still would be convenient to have as an option...
[Corion]: hippo: Hmmm - yeah, I could document it and wait for code implementing that option to show up ;-D
