## Customer Impact

- [X] Customer reported
- [ ] Found internally

Customer reported that they saw GC deadlocks after upgrading to .NET 10.
This PR is the cause. After revert, deadlocks went away.

## Regression

- [X] Yes
- [ ] No

## Testing

A private build was shared with the customer and confirmed that this PR
was the cause of the regression.

## Risk

Low. This will return us to the .NET 9 state. This PR was intended to
work around issues with high pinning scenarios, but the previous state
was well-understood and acceptable.
