--- Comment #2 from Alan Somers <asomers@FreeBSD.org> ---
Rick, have you every seen a bug like this?  To summarize:

* One thread alternately truncates, extends, and reads a file
* Another thread stats the same file

After a few seconds, one of the read operations returns more data than the =
file
ought to contain.  It usually rounds up to a 64kB boundary, but not always.=
  I
can reproduce it with the NFS client, but the OP says it happens in fuse, t=
oo.
