Maybe this is the time to ask.
I am using Linux Debian, and getting Apache 2, perl and mod_perl 2 from
there (apt-get).
I have never been quite sure which mpm the packager decided to
configure, as the apache2.conf contains parameters for prefork, pthread
and perchild. So,
a) which is the best way to find out ?
b) if it happened to be "worker" or something, could I just change that
to "prefork", or is there more to it ?

(Also so far, even if it is using a threaded mpm, it does not seem to
have any deleterious effect on my systems, which are pretty stable).
