Sure. I tried to be helpful there, but maybe I need to be more
specific. The ref from my previous post, Google-able as "The
C10K problem" is good but now a little dated. System support for
threads has advanced far beyond what Mr. Meyer dealt with in
programming the Amiga. In industry, the two major camps are
Posix threads, and Microsoft's Win32 threads (on NT or better).
Some commercial Unix vendors have mature support for Posix
threads; on Linux, the NPTL is young but clearly the way to move
forward. Java and Ada will wrap the native thread package, which
C(++) offers it directly. Microsoft's threading now works really
well. The WaitMultipleObjects idea is a huge winner.
