When using the resource handling channel we must make sure that if we (by what is IMO a bug) try to double invoke it after having already sent a response (or tried to do so) we at least release the memory in the channel's outbound buffer. Otherwise we will leak any memory from it that was used to create the now failing to send `RestResponse`.
