I think that it is an unintended interaction with the new vtruncbuf,
or perhaps an error in vfs_bio, whereby I am not gratuitiously writing
out buffers that are wrongly sized. (That can have very evil effects,
but we have gotten by with it in the past.)
It is unlikely that it is not a problem with my VFS changes. However,
there have been some formatting changes in vfs_cluster, which the
additional whitespace could be causing problems :-).
