Non-Blocking Server Apology
---------------------------

I put this example together at the last minute for the February FAQ.  It 
makes some bad assumptions you should be aware of.  I'll fix it soon, but 
for now I'll just apologize for it.

I assume that all of the reads and writes I do are going to happen 
without blocking.  What I should really do is place not only the file 
descriptor for each socket in a cache, but also a pointer to a read and 
write buffer.  Then all reads and writes should check for things like
EWOULDBLOCK and less bytes transmitted than expected, and adjust the 
buffer accordingly.

Also, I didn't have time to run this by Andrew or others, and given the 
rush job...  well, don't be suprised if you find a few bugs.  I hope it 
is at least helpful as a start.

Good luck,
  Vic.
