There's no more buffering than is necessary.  If your data isn't sent 
pretty quickly, then you're doing something wrong.  For example, perhaps 
you're calling transport.write from a non-reactor thread?  Or in a 
never-ending loop?

Don't ever call transport.writeSomeData.  It will do something 
arbitrarily wrong.
