this tool doesn't support multiprocess, right? #31

I read through the documentation and also try it my self. this tool doesn't support multi-processing profiling, right?

Correct, on its own it does not do anything outside of the python process it is used in.

If you start it in multiple interconnected processes, you will get separate traces and whenver one process waits on IPC from another it will just show as that syscall/function waiting (ex: a blocking read, or a blocking select/poll/...).

thanks for rthe quick answer, I will find other tools to do the job.
