Perhaps I'm getting hung up on the semantics. We use it more to farm out function calls, rather than passing content or delivering large messages. The one time I tried to use it for large amounts of data I did have issues with memory and latency. For simple RPC-style use (millions per day) though, our server has been stable (no change in memory or latency) for months without a restart.
