It has a serious problem: od.c and sd.c break the the EOF handling by
restoring bp->b_bcount.  It is now possible to write beyond the end of
a slice or partition.  This can probably be fixed quickly by rescaling
bp->b_bcount instead of restoring it (the same as for bp->b_resid).  I
don't have time to test this now.
