- When using a claim with immediate allocation and a pod referencing that claim couldn't get scheduled, the scheduler incorrectly may have tried to deallocate that claim. ([#122415](https://github.com/kubernetes/kubernetes/pull/122415), [@pohly](https://github.com/pohly))

// A Pool is safe for use by multiple goroutines simultaneously.

// Pool's purpose is to cache allocated but unused items for later reuse,
