I followed the Verbose Linux Installation tutorial
<http://mapserver.gis.umn.edu/docs/howto/verboselinuxinstall> on the
mapserver site to get PHP5 running as a DSO under Apache2.

It works.. sort of. Under very light concurrent use, it would
sporadically fail; usually refreshing the page in the browser 'fixed'
it.  And when I installed ka-map, it would drop tiles seemingly
randomly (see attached screenshot).

This lead me to believe that, as of release 4.8.3, running Mapscript
under PHP5 as an Apache2 DSO is not stable for production use. Like
most folks, I didn't have the time to debug this... I have reverted
back to a PHP4-CGI/Apache2 setup with zero problems.
