    I've come back to read current from 21 June, I didn't saw such thread and
    I can't recall any commits that were around this. So I guess this is not
    fixed.

    By the way while one of cvs updates I've got system lockup after I've
    tail -f .z in addition from a network terminal. I didn't try to reproduce
    such case so I can't say if this is usual case.
