Author Can TCP_NODELAY be turned on and off in a single session?

Hi,

Can one toggle TCP_NODELAY (disable Nagle) off for part of the time during a
connection (maybe for some back and forth short protocol interaction) and
then on for another time period in the same connection (say for a more bulk
data portion of a protocol)?

I can't think of any reason why not.

Since Nagle has no affect on back and forth short protocol interactions,
why would you want to?
