But all that is required is for the block I/O calls to ask the FSTs
to flush their caches before proceeding with the block I/O.  In any
case this is a fixable problem.  (On UNIX it is solved by assuming
that the filesystem is not mounted during a "raw disk" I/O operation,
and it is the user's responsibility to ensure this condition.  On
GS/OS another approach would be required.)
