$ inc doesn't work on /usr/mail/dwallach, but it works just fine on any other
$ file out there.  inc will hang for a minute and then print:

$ inc: unable to lock and fopen /usr/mail/dwallach

$ Relevant file info:
$ drwxrwxr-x   3 root     mail       20480 Jun 13 19:08 /usr/mail/
$ -rw-rw----   1 dwallach mail       14016 Jun 13 18:52 /usr/mail/dwallach
$ [...]

Do this:

	chgrp inc
	chmod g+s inc

That will do it.  I had to do this on a 3b2 running System V too.
