I also found out that running 2 & 3 at the same time produces race condition so I have put a mutex on them so that they dont run at the same time. The signal handling in totally messed up too. I think lldb-mi should be changed to be a single threaded app (or first 2 threads should be merged at least). It will get rid of a lot of complexity and these problems.

I agree that we should merge 1st and 2nd threads.
Is there any chance that you will be working on it?
