Performance issues in cups 1.3

[Bernd Krumböck]

Found the reason for our first performance issue:
Sometimes we send more than 200 jobs in a short time (1-3 minutes). Sadly there is a timeout with 10 seconds between each job.

The printer can process an print a job within 0,5-3 seconds.

I assume the "check for any active jobs" in the function select_timeout causes our performance issue.

Don't exactly know why this timeout is needed? Is it possible to avoid (or change) this timeout?
