Flushing buffer during page delivery

Hello --

We have our apache children flush the buffer when generating a page  
after emitting the JS/CSS includes, after emitting the page framework,  
etc.  However, despite that we're flushing the buffer to Varnish, it  
doesn't seem to deliver any of the data to the user until the page is  
complete.  Although the page generation time is minimal, flushing the  
buffer early lets the user's browser start pulling dependencies while  
apache spends another 100ms or so delivering the rest of the page.

Is there any way to get Varnish to flush the buffer regularly or  
accomplish this in some way?
