  Dave,

I agree that on larger systems this doesn't really make sense, but on 
embedded platforms this can save some code space since applications can 
get rid of their FIFO listeners and have strictly socket listeners.  
That's why I made it an option that could be disabled by default.

Do you know who originally suggested that "creepy crawlies" are 
introduced by allowing sockets to be opened?  I'd be interested to know 
how this could affect security, if at all.

-Jeff
