Subject: [RESEND x4][PATCH 0/3] test-ww_mutex improvements

Hey all,
  I wanted to just resend again my improvements to the test-ww_mutex
test driver. These changes have been particularly helpful for
tripping issues in the proxy-exec series.

Despite sending these a few times, I've not gotten any response.
I get its sort of a minor test driver, and isn't super urgent, but
it would be nice to move these forward upstream instead of having
them carried in one of my branches and having to remember to pull
them in when I test with vanilla upstream trees.

Let me know if I should be cc'ing someone I'm missing to get these
reviewed and eventually pulled in.

thanks
-john
