I probably didn't express this point in an impeccable way. Let me
rephrase it
Even though Tcl_Flush (and implicitly the output method of Rivet
channel) could be called when everything is done just before returning
to Apache (true for most web pages), as a matter of fact parsing a
subtemplate causes the same call to Tcl to occur and therefore becomes
impossible in this case to change the headers. This is incoherent and
fuzzy and should be fixed
I hope the rest of my message is understandable.

I've been repeating with Rani the same point every time he brought it
up: redirection should be done ASAP and before sending any data to the
stdout. I maintain that for any "sensible" page (most web pages size is
well < 1000000) data are sent when mod_rivet calls Tcl_Flush, therefore
redirection can occur before that point, but it's not true every case.
Rivet_ExecuteAndCheck calls Tcl_Flush which in turn causes Rivet
channel's output procedure to be called by Tcl. And this happens also
when the ::rivet::parse command is called (which calls
Rivet_ParseExecFile and then Rivet_ExecuteAndCheck)
