Implement mutex locking in the Arena class to ensure thread-safe operations across Allocate, AllocateAligned, and related methods.
Refactor Arena's internal logic to prevent deadlocks and ensure efficient memory allocation in a multithreaded environment.
Add a comprehensive unit test in arena_test.cc to verify thread safety, focusing on concurrent memory allocation and deallocation.
Update documentation in arena.h to reflect new thread safety features and provide usage guidelines for multithreaded scenarios.
This commit addresses the need for thread-safe memory allocation in high-concurrency environments, improving the robustness and reliability of the Arena class in LevelDB.
