- Fixes a deadlock from a previous fix to keep module loading
and function tracing text modifications from stepping on each other.
(this has a few patches to help document the issue in comments)
- Fix a crash when the snapshot buffer gets out of sync with the
main ring buffer.
- Fix a memory leak when reading the memory logs
