that's not my impression.  /cache is an ext2 filesystem:

relax.7% ls -l short.bonnie.sh
-rwxr-xr-x  1 chas users 55 Aug 18  2002 tmp/short.bonnie.sh
relax.8% fs flush short.bonnie.sh
relax.9% df -k /cache
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sdb1               482214    427736     29579  94% /cache
relax.10% cp short.bonnie.sh /dev/null
relax.11% df -k /cache
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sdb1               482214    427744     29571  94% /cache

i didnt include getcacheparms but it only thinks the cache increased by 1k
but in reality it went up by 8k.  isnt there a list of open/active cache
files (dcache slots?)?  the bulk of cache files are closed but if you had
a fullish cache and opened a bunch of small files you could overextend.

ext2 works fine as a cache if i limit it to 1/3 to 1/2 the size of the
cache partition.
