ifile uses the semget, semctl, semop group of calls to do file locking. It
seems to work quite well, both for local and NFS files.  You'd have to ask
Harry McGavran about the details, though.

An easy way to see it in action is by running your script to build the
database and filing a message at the same time.  Filing should take longer
than usual as it waits for a chance to access .idata.

You can find the semaphore code in ifile.c.
