When you do a ipcs -opq, it show message queue numbers that are negitive:
Message Queues:

Because of the queue number, you can't use ipcrm to clear them out.  It would
be nice if the queue numbers would not get bigger then a 5 digit number.

How-To-Repeat: Use a program that creates and deletes a message queue every 5 minutes.

Fixed in rev. 1.44 src/sys/kern/sysv_msg.c in -CURRENT. I'll MFC the
