Surely apache was (and optionally still is) a more famous multi-process architecture.
But is it really a big deal?
Isn't the only difference is that in a multi-process architecture memory
is protected from other processes unless you explicitly mark it shared while
in a multi-threaded architecture memory's shared unless you explicitly mark it
thread-local?
That some OS architectures implement one or the other of these poorly -- poor
performance of either threads or processes; or poor protection of thread-local
storage -- but that seems like an OS quality-of-implementation detail. Other
differences (which thread/process gets a signal, how are file-handled shared)
seem to be minor details that vary from OS to OS anyway.
