Done.  People are definitely invited to check the code and report
bugs :) In particular, I have an issue with the way AJP handles
reusable connections: if requests follow closely, AJP will reuse the
same connection; however after a timeout (seeminly unrelated to
workers.properties options), AJP will make a new connection and never
reuse the old one (but il will not close it either!).  Does AJP
/requires/ a connector handling multiple connections (FastCGI for
example may use a farm of processes but also works well with a single
sequential one)?  I'll be glad if somebody points out to me the point
I do not get...

Yes, this is a compelling reason.  I have added the field
[default_exn_handler] to the [Netcgi.config] structure which, when
turned false, let the exception stop the program.

Done.

More later on the other points.
