Thanks for the helgrind example. I'll have to add that to my toolkit.

import threadpool
when isMainModule:
quit(QUITSUCCESS)
Running strace, I noticed that there were 12 clone syscalls made.
In nim/lib/pure/concurrency/threadpool.nim, setup is called in the main body
and creates a worker for each processor.
I think this explains why the mutex is not properly cleared as we are forking
from a multi-threaded process that is setup by threadpool.nim.
