You should not be calling private reactor methods, it will break things.
You can make the max write size (default 128 or 64kb, I forget) bigger by
setting some attribute on the transport, but again, the OS will split
things up across TCP packets however you want. This is not a very useful
thing to attempt - better to instrument firefox to only do certain size
reads.
