If any of you are running PMDF II (as many CSNet sites are), you will
discover that PMDF will not work once you convert to 4.3BSD.  It works
a little, but keeps timing out and your queue keeps growing.

Well, after a few dead-ends, we found the problem.  The following
changes should be made to your PMDF code and then the whole
package should be recompiled and relinked.
