> When running a TMUDF that returns very many rows, I am seeing the memory consumption of the UDF grow by a very large amount, proportional to the number of emitRow() calls it makes.
> From debugging I see that a call to IpcBufferedMsgStream::cleanupBuffers() is missing in function PerformWaitedReplyToClient(). For small UDFs this is probably not so much an issue, since the cleanup method gets invoked at a later point, but for very large UDFs, all the reply buffers stay allocated until the UDF finishes.
