request_rec question

[Brian Pane]

Is there anything that actually uses the
headers_out or err_headers_out fields in
the request_rec that's created for a subrequest?
Anything written to these fields appears to
be discarded upon completion of the subrequest.
We could save a couple of apr_table_make calls
per subrequest if the httpd didn't have to
create these two tables.
