I think you'll have to write the 100 response header(s) and status line 
to the underlying connection object. Otherwise, apache will think that 
the request is finished, and weird things will happen.

Simply closing the connection is not so bad - the server is free to do
that anyway. Outputting a "Connection: Close" header along with your
error mesage is good practice. That's what I use since 100-continues are
a pain in the neck to get right on the client side (Python's httplib
cannot handle them).
