I became curious and tested this by registering a PerlCleanupHandler
directly in apache. Documentation is correct - content was served before the
cleanup handler.

I know Mason quite well but I can't find any explanation for what you are
seeing... I know they try to delay sending content until the last possible
moment to ensure that any and all headers make it in. But I don't see how
they'd make it past the content phase.  Mason has an excellent mailing list,
btw - somewhere on masonhq.com. May be somebody can make sense of it there!
Good luck.
