The OS is backed by just one disk, formatted with the OS X default,
but I'm not sure I see how that's relevant to the MacFUSE case...

3 files attached:
cat.works.txt: plumber gives accurate length, cat works as expected
tail.works.txt: plumber gives accurate length, tail works as expected
tail.screwy.txt: plumber hacked to return length of 1, tail gives
output that is exactly the same as cat, except that the second char
(the "l" in "plan9=/usr/local/plan9") is missing, as if it were
"superseded" by the "p" from the length-1 read.
