If you have cooperating processes, and you want to create a pipe
at runtime, how do you pass it between processes? (wihtout having to
make a named pipe)...
In the systems I build at work, its fundaemntal. When I was first
asked to do it (and told how), I never knew it existed before...
I think bsd4.4 can pass an array of fd's, older bsd style OSes were
limited to one fd...(?)
