[PATCH] kill all threadapply processes at end of test

[Carl Love via Gdb-patches <gdb-patches@sourceware.org>]

GDB maintainers:

The threadapply test performs a number of tests to detatch and attach
threads.  When the test is all done, some detatched threads are left
running.  The following patch adds code to the end of the patch to kill
the processes that are still running.

Please let me know if this patch is acceptable.  Thanks.

                     Carl Love
