Yes, I've run into similar issues in the past also. It'd be really neat
to somehow make the SnapshotNow (and I'm guessing the whole SysCache
system) behave more like MVCC.

Perhaps.. Seems like it'd be a lot of work tho, to do it 'right', and I
suspect there's a lot of skeletons out there that we'd run into..
