Sorry, I meant to say mp2.

so it spins in the filter? Blocking? Or running it like mad? you can run:
http://perl.apache.org/docs/2.0/user/config/config.html#C_PerlTrace_

MOD_PERL_TRACE=f t/TEST t/protocol/echo_block t/protocol/echo_filter

(see the URL above how to get the tracing going). That may give you some 
better ideas of what's going on underneath and where it spins.

Debugging by proxy is a way too frustrating, so if you could try to debug 
yourself, I'll gladly answer any questions you may need to ask to get 
yourself going.

I'd start with taking those tests out of the modperl suite, and putting 
them into a dedicated test-case - that will make things faster and easier 
to debug. You do that by copying (.pm|.t) files into:
