I've looked through this series and I feel like none of these are real
bugs. It's just about type safety and being consistent. Which are good
things. I'm not sure that I like the parts where we make the variables
signed.

Here "nscheds" is the number of threads. How can we have a negative
number? I think it should be unsigned. It's way more tricky to change
the rest of the code, and leave nscheds unsigned int but I think it's
probably the right thing.
