I can think of a few uses:

	1) Portability.  How else would you write a program that polls 
the keyboard in a way that would run on both MS-DOS and Unix?

	2) An infrastructure for implementing file-system extensions, like
the sockets. 

Anyway, this thread was started when somebody asked what should they use 
instead of `select', probably because they don't know DJGPP *has* 
`select'.  They didn't tell why did they need it.
