Description of problem: When making use of a threaded application, using pkill on it will occasionally result in multiple signals being seen by the signal handler. pkill -P 1 eliminates the issue. Also, using procps 3.0.15 gives the correct behaviour. Is procps, as shipped with RHEL, *not* NPTL-aware?? Version-Release number of selected component (if applicable): procps-2.0.13-9.2E
Fixed in 3.1.15
