  Log:
  Block SIGURG while reading from the control channel.
  
  Rationale:
  
  SIGURG is configured by ftpd to interrupt system calls, which is useful
  during data transfers.  However, SIGURG could interrupt I/O on the
  control channel as well, which was mistaken for the end of the session.
  
  A practical example could be aborting the download of a tiny file,
  when the abort sequence reached ftpd after ftpd had passed the file
  data to the system and returned to its command loop.
