[lvm-devel] [PATCH] Add blocking/non-blocking test for vgremove.

[Dave Wysochanski]

While a big ugly, this tests Milan's recent fix to take blocking orphan
locks when wait_for_locks = 1, the fix that addressed:
https://bugzilla.redhat.com/show_bug.cgi?id=578413

Other ways to test this sort of functionality are certainly welcomed.
This patch is at least a start at test coverage of such blocking/non-blocking
functionality.
