I intend to commit the following to HEAD in the forthcoming days,
unless there is an objection to this change.
When exitting upon an abnormal signal, yppush_exit() should not
attempt to clear its pending jobs list, as this could trigger another
signal, and cause an infinite recursion. What yppush_exit() tests
in order to determine whether to flush pending jobs is the
yppush_joblist chained list, so this is what needs to be cleared
in that case (not the yppush_jobs counter).
