As Andrew pointed out, Squid gains some efficiencies by using
a single file number (4 bytes) as a pointer to the on-disk
object data. The algorithm which maps file numbers to pathnames
must be consistent. When you add more 'cache_dir's you alter
the mapping algorithm, so cache files will be lost.

Its a similar problem with the size of each cache_dir. We need to
come up with an algorithm whereby you can adjust the relative
sizes without affecting the mapping to pathnames.
