I tried this one, and it's buggy.  You need to have a line like:
   conn->data = NULL;
somewhere around the brigade cleanups, or after a couple of requests you'll 
SEGV because conn->data->buffer isn't valid anymore.

I haven't tried the poll-timeout, but would tend to agree with Paul on it's 
usefulness.  Currently mod_jk doesn't flush on output (of course, it thinks 
it's still httpd-1.3 and calls ap_rwrite, so maybe not the best example :).

The closest thing to the AJP/1.4 proposal would be:
  http://tomcat.apache.org/connectors-doc/common/ajpv13ext.html
Of course, no Tomcat version currently supports it.  It wouldn't be that hard 
to add a CMD_AJP13_FLUSH to Tomcat (with a Tomcat configuration option to turn 
it off so it doesn't freak-out mod_jk :).  But as Will says, that discussion 
belongs on dev@tomcat.
