Issues tangential to win32 support

There are some issues that the whole idea of a win32 port should bring up.  
One of them is whether or not postgresql should be rewritten as a 
multi-threaded app.

If postgresql will never be rewritten as a multi-threaded app, then 
performance under Windows is likely to ALWAYS be slow, since that 
multi-thread is the preferred model for good performance on W32.  note 
that many Unixes prefer multi-threaded models as well (Solaris comes to 
mind) so there's the possibility that a multi-threaded postgresql could 
enjoy better performance on more than just windows.

If postgresql IS going to eventually be multi-threaded, then the whole 
win32 port should probably be delayed until then, since it would solve 
many of the issues of fork() versus createprocess().

Just my thoughts on it.
