  1. mx_flock: Don't unlock before close 

    We don't need to call flock(fd, LOCK_UN) for a file we are going to
close anyway, so don't do it.

This might make a difference if the lock fd was dupped into another fd.

  2. mx_flock: Add mx_funlock_nodelete 

    Add function to release the lock without removing the logfile. This is
useful for forked children, which inherited the lock and just need to
give it up.

  3. mxqd: Unlock but do not delete lock file in reaper 

    The reaper inherits the locked lock file and needs to unlock it. Use
mx_funlock_nodelete instead of mx_funlock so that the lock file is not
removed.
