+1 on concept. But I'll defer to Roy's review of the patch itself.

When the application first attempts to read *body* content from the input
filter stack, the HTTP_IN should generate the 100-Continue, if appropriate.
Doing it there will enable it to work for both filter-based modules and the
old-style API.

It's a little tweaky for an input module to generate output, but we already
do that in the SSL module, so we've definitely seen that before.

Note that HTTP_IN can even discard the body in case of an error.
