Write batching

[Yang Zhang]

Is there any way to batch up outgoing messages at a level near the 
socket and control when they are sent (e.g. when a buffer fills up, when 
some time expires, etc.)?  Is there a channel handler that does this, or 
would this not be fitting for the pipeline architecture?  (We're trying 
to reduce the number of syscalls, so Nagle's algorithm would not help 
very much here.)

Thanks in advance.
