Description

PR #1785 fixed a data race condition by adding locking to the internal Urkel tree cache, but the implementation could be improved further by distinguishing between accesses that need only a read lock and accesses that need a write lock.

Acceptance Criteria

  • Urkel tree internal cache uses RWMutex for locking.
