Code Red and friends didn't even tickle a bug (in non-Microsoft servers), yet choked many non-Microsoft down due to the sheer number of requests. A `Code Red for Win32 Apache Chunking' would probably not spread as much (unless there is way more Win32 Apache than I think), but the number of requests generated could still be large --- and have special impact on Apache < 1.3.26 servers.
