> Yonik uncovered this with the TestRealTimeGet test: if a flush-all is
> underway, it is possible for an incoming update to pick a DWPT that is
> stale, ie, not yet pulled/marked for flushing, yet the DW has cutover
> to a new deletes queue.  If this happens, and the deleted term was
> also updated in one of the non-stale DWPTs, then the wrong document is
> deleted and the test fails by detecting the wrong value.
> There's a 2nd failure mode that I haven't figured out yet, whereby 2
> docs are returned when searching by id (there should only ever be 1
> doc since the test uses updateDocument which is atomic wrt
> commit/reopen).
> Yonik verified the test passes pre-DWPT, so my guess is (but I
> have yet to verify) this test also passes on 3.x.  I'll backport
> the test to 3.x to be sure.
