:Maybe but the bug also occurs w/o unmounting (cf my previous email).
:
:Freebsd allows forced unmounts but does not crash.  Linux on the other
:hand behaves as you suggest (forced unmount fails).

    In our case we want the forced unmount to succeed, though personally
    speaking Linux is probably more correct simply because when we override
    vnodes in a forced unmount there is always the possibility of a race
    against something.  For now though I want forced unmounts to succeed.

    I'll check it out.
