Handy for receiving and processing messages in a realtime context. The messages could be channelled through the realtime context without deallocating any memory there. Instead they are returned back to the producer that either recycles or drops them. ## License Licensed under the Mozilla Public License 2.0 (MPL-2.0) (see [MPL-2.0.txt](LICENSES/MPL-2.0.txt) or ).
