Log:
  Process address resolve requests at least one time per second in ibcore.
  
  When setting a large address resolve timeout it was observed that the
  address resolving would succeed at the timeout and not when the address
  was available. Make sure the address resolving requests are processed no
  slower than one time every second.
  
  While at it use "int" for jiffies instead of "unsigned long" to match
  FreeBSD ticks.
