Thanks again! Looking forward to it.

Yeah I agree. Not sure about the per-thread hypothesis.

This was my next step. I thought context id based implementation would
let me get familiar with what I am doing quickly and then I can take
up context-switch-time bkpt insertion.
But you beat me to it totally!

Going through your patch and will be trying it soon. At first sight,
seems the gdb changes aren't there in that link. Can you point me to
the gdb changes?

Thanks,
