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):
Fixed in 3.1.15
