[Feature Request] thread/multiprocessing traces

[beasteers]

Omg first off, I just found this and I love this package!

I haven't looked into the source to see how feasible this would be, but it would be great to be able to visualize the stack traces for each running thread/subprocess. (I'm sure thread traces would be easier to handle than processes). This would be very useful in trying to debug where thread.join is hanging for example.

Thanks, I'm glad you like it! I'm actually surprised how popular this library seems to be. I just thought it was a fun idea and hacked it together pretty quickly. I don't actually know how useful it really is, I've barely used it myself. Has it helped you in a real situation? Or is it mostly hypothetical?

Visualising each thread should be straightforward but would require significant work which I'm not willing to do. I can help with a PR though.

In the meantime you can trace multiple threads but you have to call trace for each thread and specify a unique port each time.

For your use case of trying to find out where a thread is getting stuck, consider my other library snoop.
