That is not how Apache prefork MPM works.

It is not how the newer worker and event MPM's work either.

The end state sounds more like how single process multi-thread
works.

And I don't understand the "put all the client context into
shared memory" either. Are you saying that if socket descriptors
are put in shared memory then any process that map that memory
can use those sockets????
