  Log:
  When generate a core dump, use advisory locking in an advisory way:
  if we do acquire an advisory lock, great!  We'll release it later.
  However, if we fail to acquire a lock, we perform the coredump
  anyway.  This problem became particularly visible with NFS after
  the introduction of rpc.lockd: if the lock manager isn't running,
  then locking calls will fail, aborting the core dump (resulting in
  a zero-byte dump file).
