Though some of you might find this interesting:

With Apache Server v2.0 comes a serious reorganization of code that makes it
much
easier to take full advantage of a platform's features, especially non-unix
platforms like
OS/2. The enhancements that have been implemented in Apache for OS/2 v2.0
include

- Multi-threaded, multi-process design for greatly reduced memory consumption,
better
performance & high stability. An access violation causes only the death of the
offending
thread, not the whole server. The fork() system call is not used to create
server
processes, removing the memory problems that v1.3 could encounter.

-Bypassing of the EMX unix compatibility library for both file and network I/O
by using
OS/2 API calls directly for better performance.
