Sysctl knob(s) to set TCP 'nagle' time-out?

I'm wondering if anything exists to set this.. When you create an INET
without the 'TCP_NODELAY' flag the network layer does 'naggling' on your
transmitted data. Sometimes with hosts that use Delayed_ACK
delayed_ack) it creates a dead-lock where the host will not ACK until
another packet and the client will not send another packet until it
gets an ACK..
The dead-lock gets broken by a time-out, which I think is around 200ms?
But I would like to change that time-out if possible to something
I can't really see any sysctl knobs that have a name that suggests
So does anyone know IF this can be tuned and if so by what?
(And yes you could solve it by setting the TCP_NODELAY flag on the
but not everything has programmed in options to set it and you don't
have access to the source, besides setting a sysctl value would be much
simpler than recompiling stuff)
