sub-second sleeps on BSD 4.2

[Donn Seeley]

This is another perennial question...  This time, though, I'll break
down and post my 'all-singing, all-dancing' fsleep() routine to
net.sources where everyone can beat on it.  fsleep() is the same as
sleep() but it takes a floating point argument instead of an integer
one.  I put some work into it trying to find all the race conditions
and timing problems but I still can't claim perfection for it;
corrections are welcomed...
