Ok, version 5 of this patchset. The frist two patches are identical. The second two have some minor cleanups
Change notes:
1) Patch 3 has the wait_for_dump_helper modified a bit to remove the ISFIFO check. Instead, we use the ispipe test in do_coredump.
2) wait_for_dump_helpers is modified slightly to move the readers/writers modification outside of the while loop, so we don't have to constantly churn those values.
3) Augment the test to call wait_for_dump_helpers to include a non-zero check on core_pipe_limit. This restores the documented sysctl behavior that I intended, which only allows for waiting on processes when core_pipe_limit is non-zero.
