> I'm grabbing my own {{RowLock}} on a given row and then I want to do an ICV on the row
(among other things) while I hold the lock.  Unlike {{Get}}, {{Put}} and whatnot, there's
no way to specify your own {{RowLock}} when doing an ICV.  Technically, you can live without
this since you can get just a {{Get}} followed by a {{Put}} after having manually incremented
the value, which is guaranteed to work as you hold the {{RowLock}} on that row, but it would
be nice to be able to just do an ICV.
> Right now, {{incrementColumnValue}} attempts to lock the row again (which is normal),
thus causing my client to "deadlock" itself until its {{RowLock}}'s lease expires.
