creeping fsck bug with System V FIFO

[Stuart Cracraft]

I have a System V machine; When I do an fsck, it reports
Possible file size error, and then "I=nnnn" where the
inode is named.

When inspected with ncheck, this inode turns out to be
that for /usr/spool/lp/FIFO. If I delete this file and
then run fsck again, I figured it would clean things up.

A half hour later I discovered FIFO was back again and
fsck was getting the same error again.

Any idea what's happening oh great wizards?
