Your only need to loop 25 times to check 800 file descriptors, so whats
the big deal???  I look at fds_bits (the array of longs under fd_set), for a 
non-zero value, then use ffs to figure out which descriptor(s) are active for 
a large number of open descriptors.  I then clear the bit, and continue 
checking where I left off.  Fairly inexpensive.
