  Prevent abnormal termination of a child daemon process when created
  by a parent that is a session leader (e.g., login shell) by ignoring
  SIGHUP before calling fork(2) and then restoring SIGHUP's action
  after setsid(3).  Based on the patch by Martin Kammerhofer
  <mkamm at gmx.net>.
  This has been in -current for 8 months with no reports of adverse
  affects.
