You have to remember you have open, read, possibly seek, and close, 3 to
5 times per second. meter-0.2 or Portato code in the kernel would add 8k
at the very most, as well as better interactive time, especially on
smaller 386 systems.

We have to think of the humble 386SX16 users too... I have a P5, but a
386, too. Portato makes the system load go up noticeably. Not to 2.0 or
anything, but noticeably.
