Hey folks,
Did you know that (at least on x86 linux), if you have a multi-thread
program and you execute a target function call, all the threads get to
run? Doesn't that seem like a bad thing? Wouldn't we really rather
only run the thread that is executing the target function call?

Eeeeek! I think I agree with you here; that's the logical behavior. It never occured to me to try.

What happens if the target function wants to interact with another thread? e.g. wait on a mutex being held by another thread?
