I guess locking will spend some time waiting for the lock in some cases, so removing unneeded locking should be a good thing. Also, updateStackLimit() seems to be called many times from other places than the api locking, so I believe it makes sense to check whether a new fiber is running. Please correct me if I am wrong :)
