Adam Holmberg updated CASSANDRA-16097:
--------------------------------------
Test and Documentation Plan:
Testing:
I had a manual test (linked in comments) that reproduced this with 100%
certainty over time on my platform, but it was not deterministic. I'm not sure
if it's worth converting into a dtest because it's based on timing for both the
local error, and spec exec decisions are not deterministic.
No docs
Status: Patch Available (was: In Progress)
