I'm already knee deep into a solution for Linux and my Windows
implement was already tested before I started (I had the code from
Delphi).  I just had to create framework for methods that fit for all
OSes.  So in this regard the semantics of my app are already fleshed
out.

But APC QUEUE method was unique to windows.  It is called via the
thread after it cycles and awakes during execute.  I found that very
useful for protecting memory access from other threads.

The trick would be to find the equivalent under Linux.
