  Modified files:
    usr.sbin/portsnap/portsnap portsnap.sh 
  Log:
  Use some features of sh(1) which I didn't know about until today ("read"
  can read two variables at once; and suffix pattern deletion) to make the
  extract command fork fewer processes.
  
  With the portsnap snapshot and the ports tree in swap-backed memory
  disks on my 1.4GHz laptop, this reduces 178800 processes and 195/56/126
  seconds of real/user/sys time to 44600 processes and 103/34/60 seconds.
