Thank you for this. This is really useful information. I recently adapted some garbage collection code to add register scanning. I can imagine all sorts of subtle bugs where things go away randomly. One problem I have with my multithreaded code is that sometimes a thread crashes and the logs are so long I don't notice. From my perspective the thread is just not doing anything. Sometimes the absence of behaviour can be really tricky to debug!
