ValueError: generator already executing

[felixlu]

I am using objectpath in my dramatiq workers, with both multiple processes and threads enabled.
Recently I found many "ValueError: generator already executing" in the error log.
However I cannot reproduce the problem with the exactly same data and code manually.
I googled the exception, and it turns out that's probably a thread-safe related problem.

ObjectPath is not thread safe. It uses bunch of global etc. Due to performance issues I didn't wrap the code into a class, but you can easily do it if you like. Adrian
