Subject[patch 19/22] Fix suspend with traced tasks
-stable review patch.  If anyone has any objections, please let us know.

------------------
strace /bin/bash misbehaves after resume; this fixes it.

(akpm: it's scary calling refrigerator() in state TASK_TRACED, but it seems to
do the right thing).
