Interpreter scope

Hi,

the default interpreter scope is request. That means a
certain interpreter is 
locked during the whole request cycle. I use modperl mostly
in the 
pre-response phases plus sometimes as an output filter. But
I use pnotes to 
pass data between the phases. If I understand it correctly
this forbids a 
handler interpreter scope. Now I'd like to release the
interpreter in most 
cases just before the response phase. So it can be reused by
another request 
while the current request sends its data over a possibly
slow network.

Is that reasonable?

Is there something like
$r->release_interp_after_this_phase()?

If not what is the right place to start looking/patching?
And what pitfalls 
are there to watch out?

   Have you looked into using a lightweight front end setup
to handle
   this?  I've had great success with the more traditional
light/heavy
   Apache setup with mod_proxy, perlbal is awesome, and know

   many people who use things like lighttpd or pound.

You might try using notes() instead, since I don't think it
cares about 
which interpreter is used.  You can use Storable to stuff
things into it 
if your data is more than just a string.
