Akihiko Odaki 1063693e1c contrib/plugins: Use GRWLock in execlog ... execlog had the following comment: > As we could have multiple threads trying to do this we need to > serialise the expansion under a lock. Threads accessing already > created entries can continue without issue even if the ptr array > gets reallocated during resize. However, when the ptr array gets reallocated, the other threads may have a stale reference to the old buffer. This results in use-after-free. Use GRWLock to properly fix this issue.
