Package: pound
Version: 2.6-3.1
Severity: normal
Dear Maintainer,
the pound source code contains a bug waiting for a semaphore. After the
semaphore has been signaled a thread has to check again if the queue contains
entries. In a system with a high number of threads that is likely not the case.
Therefore, a while-loop instead of an if is required.
The patch is quite simple:

+++ pound.c 2014-02-06 14:04:02.604718653 +0100
