Well, on unix, you could use the (still experimental, according to 
the docs) shared memory functions:


There's also the apparently more mature, but less portable 
semaphore/shared memory functions (also Unix only) here:


I've never used either of these.

Maybe you could explain what you're trying to do a bit more (and what 
platform you're on). I can't see where loading separate copies of the 
variables would be much of a memory issue, unless you have large 
numbers of variables, very long strings stored there, and hundreds of 
apache child processes.
