Bugfix: various issues that snuck in during rewrite - Turns out unmanaged threads get destroyed by engine, so needed to add deferred clean up of collected telemetry - this fixed editor crashes and crashes in export thread - I accidentally recorded allocations for worker threads only - flipped to record main thread only - I was emitting methods for MethodExit and MethodException marks, which is unnecessary - cleaned up Still need to fix timestamp conversion on export, that'll be next Tests: exported snapshot from Editor's Craggy
