What changed?
We now fail any command batch that would leave us with too many pending cancel requests.
Why?
To enforce workflow size constraints.
How did you test it?
I added a large integration test that verifies that a workflow that tries to cancel them all at once fails, but that a workflow that attempts to cancel them in batches no greater than the maximum number of pending cancel requests.
Potential risks
This will likely break any workflows that attempt to cancel a large number of workflows, from within a workflow in rapid succession.
Is hotfix candidate?
