We could ask the Windows packagers to set the appropriate
configuration bits when building Neon, i.e.,

   #define HAVE_SETSOCKOPT 1

This enables Neon to turn off Nagling (thanks to Mike Pilato for
explaining the convolutions to me), which it will do, because
apparently it already knows about the lossage resulting from the
combination of Nagle and delayed ACKs.

Maybe Joe Orton can say whether this is a sane approach?
