o look for 'XXX' in the source, they mark some bits of code that need work
o port to apache 2.0
o multipart_buffer_headers punts on headers more than 5k (which could
happen with a really long form input name, for example). better than
the old behavior of locking up, but we could be clever and actually
handle this.
o should probably handle Apache::Request->param http://blah.com/?foo
like CGI.pm does (turn it into a param named "keywords")
o libapreq.so ?
o mmap upload files ?
o port to Mac OS/X
o improve/automate build process for c, dtcl (autoconf support?)
o test suite ?
o optional build/link of libapreq.a directly into httpd?
