A Foundation tool manages its own run loop, if it even has one. So 
how you manage autorelease pools is entirely up to you.

If you're using an NSRunLoop, you might create a pool before 
processing each event, and release it after, just like NSApplication 
does in an AppKit app.

If your daemon is a network server that accepts incoming connections 
via BSD sockets or CFSockets, you might create a pool before handling 
each incoming request, and release it after.

Then don't do that. :-)
