I don't think that's a very fair assesment.
It is true that some crons (I can only speak
of my own and Vixie cron for certain) make
use of such functionality, but so could many
other long running daemons. Almost anything
which implements some sort of caching, e.g.
a finger daemon that caches .plan s.
Specifically where none of the caching modules
on CPAN are appropriate. They are centered
around IPC. This is useful for caching where the
filesystem is authoritative and significant
processing must be done on every file.
