  SVN rev 198132 on 2009-10-15 14:18:35Z by luigi
  
  A small change to avoid calling gettimeofday() too often
  (hardwired to once every 20us at most).
  
  I found out that on many machines round here, i could only get
  300-400kpps with netsend even on loopback and a 'deny' rule in
  the firewall, while reducing the number of calls to gettimeofday()
  brings the value to 900kpps and more.
  
  This code is just a quick fix for the problem. Of course it could be
  done better, with proper getopt() parsing and the like, but since
  this applies to the entire program i'll postpone that to when i have
  more time.
