Or even better, capture the error, and if it is Address in Use, place a 
error message ("Port busy, retrying in 15 seconds...").  Then sleep, and
retry.

I'm a bit surprised that SO_REUSEADDR isn't supported (but then, I never
tried 
it:-).

Anyway, you can safely take this out, usually. Setting SO_REUSEADDR is
mostly 
used to be able to quickly listen to a port again after the previous program

listening to that port has crashed. Normally there is a timeout of about a 
minute.

If you take out this option the only thing you may notice is that if your 
program is aborted and you immedeately try to start it again you will get an

"Address in use" or something similar. Wait a minute and it will go away.
