Description of Problem:

up2date does not close fds for packages it is downloading. Default ulimit is
1024, so I think up2date will consistently fail to run if a system has that many
packages out of date. Particularly since this happens both with newly downloaded
files and ones already in /var/spool/up2date.

Version-Release number of selected component (if applicable):

up2date-2.57-1

How Reproducible:

Always.

Steps to Reproduce:
1. Run up2date with many updates to do.
2. Midway through the process, do a "lsof -p <PID> | less"

Actual Results:

There are lots and lots of open /var/spool/up2date/* files.

Expected Results:

Just the one it is working on is open.
