That's true.  When the Apache process forks, each child process has different 
copy of the address space.  Same address, different contents.
You will need to use some explicity shared memory, either from a mmap'd file or
a shm segment.  This will imply a custom memory allocator and custom malloc()/
free() - like functions.  But you will need to make python use this shared
memory, and I have no idea if that is possible.
