#5 Old session files not getting deleted

[Mike Sugarbaker]

Our jury-rigged custom session-files dir (intended for
shared hosting and others who don't want to use /tmp)
has a tendency to fill up over time, eating up those
precious MB for those with disk space quotas. Full-disk
errors have a tendency to make CoCo pages show up blank.

Recommendation: go ahead and implement DB-based
sessions. Failing that, investigate settings to get
built-in PHP sessions functionality to behave. Or
possibly the other way around.
