:I should point out that FSX can be used against any filesystem, and

Well, I already found and tracked down a softupdates bug revealed
by this code... definite server panic, especially if an NFSv2 mount
is used.
I shot some mail off to Kirk with a proposed fix for that.
With both NFSv2 and NFSv3 I get user-process bus errors with the
truncate()/mmap() combinations being used. I'm tracking that down
now.
