If resize is called when there are more than *new_size* greenthreads already working on tasks, they will be allowed to complete but no new tasks will be allowed to get launched until enough greenthreads finish their tasks to drop the overall quantity below *new_size*. Until then, the return value of free() will be negative.

Returns the :class:`GreenThread <eventlet.GreenThread>` object that is running the function, which can be used to retrieve the results. If the pool is currently at capacity, ``spawn`` will block until one of the running greenthreads completes its task and frees up a slot. This function is reentrant; *function* can call ``spawn`` on the same pool without risk of deadlocking the whole thing.
