Subjecttest9 not using buffers
Alpha DP264 (UP), SCSI, floppy

If I do a dd if=/dev/zero of=/tmp/moo count=100000, I don't see any
increase in buffers, as reported by vmstat. Furthermore, if I read from
/dev/fd0, it used to buffer the whole thing, so a second read would be
fast -- now it hits the floppy again.

I ran some fairly large things when I first booted, and swapped some stuff
out -- I don't know if this would've happened before. But now my buffers
number is way small:

procs memory swap io system
r b w swpd free buff cache si so bi bo in ...
2 0 0 4568 444984 38008 141744 0 0 4 10 9 ...

and it won't grow much bigger than that no matter what I do.

What's up with buffers?
