Tries to wake `val` threads from the pool. This is done bypassing the
current concurrency level (`OC` stands for `OVERCOMMIT`). On success,
the number of woken threads is returned, it can be 0, but it's the
real count that has been (or will soon be) woken up. If it's less than
required, it's because there aren't enough parked threads.
