Yup, it sure is.

If you want to be a Real Man, then you can use _apache.mpm_query to verify
that you're running single-threaded :-)

btw, if you're going to rely on prefork, then why don't you just use the
exit handlers for the process rather than worrying about Apache's pool
cleanup handling? If you're doing the latter to work within the Apache
framework, then you really ought to keep threads in mind :-)
