Apache with prefork mode can share the memory? Sorry I didn't know it.
Sharing memory between multi-processes need extra programming, I don't
know apache has done it already.
well, it's not "shared memory", it's just the simple forking model which
doesn't copy memory, for example module code or big configuration data.
only if you change some of the data the process copies the memory page.
