It's not possible. Perl allocates its own memory. You can't tell it where it to put things. As discussed many times on the list, copy-on-write helps with this on prefork systems. On threaded systems, Perl shares the parsed code, but the symbol table is duplicated for each thread, so it ends up using more memory than prefork. You can read more about copy-on-write in the mod_perl docs or at modperlbook.org and there is more discussion about threads and how they affect memory in the list archives. - Perrin
