Commit Message

Release the semaphore permit when SizedGroup skips a canceled preemptive call

With Preemptive the permit is taken in Go before the goroutine starts. When
the goroutine then found the context canceled it returned without unlocking,
so each such call took one permit away from the group for good. The unlock is
now deferred and covers the skip path as well as the normal one.
