The temporary leak is occurring in the request handler. <-time.After() is not garbage-collected before expiration and shouldn't be used in such a frequently called method.

Performance profile (done on ~1000 API calls using the Stream API):
Fixed memory leaks in GoVPP core stream and request handler.
