------------------------


The bug is described in detail in Issue 1679

In case of tight integration slave tasked killed (coverd by testsuite) the
qmaster sends in one packbuffer two SIG_KILL to the master task. It seems this
is caused because the qmaster mark the job as deleted because one execd reports
one slave died and in the same time another execd sends the load report
intervall with the job as running.

The qmaster should check if the job is already signaled in one packbuffer and
should discard the second kill
