Me too.  +1 on the patch.

Yep, which is why I was surprised to hear that ONE_PROCESS was causing
NO_DETACH to be set as well -- that doesn't make any sense to me.  There
is nothing more frustrating for me than being in the middle of a "how to
debug apache" class and having to explain these new options.  ONE_PROCESS
should mean only one child process, since that's exactly what a developer
needs to attach to a child before a request is sent.  -X should mean that
we are inside a debugger and need all of the options to make stepping
though a process easy.
