Under both RedHat 5.1 and 6.0, the new lpr-0.44-0.5.2 and
lpr-0.44-1 post multiple copies of a document to the queue
when only one is sent, e.g. lpr paper.ps sends a copy and a
few minutes later it does it again, and a few minutes later
does it a third time.
The daemon also dies under both 5.1 and 6.0 after multiple
copies are posted.
Should be fixed in the 0.46-1 errata.
