wedged
     
        1. To be stuck, incapable of proceeding without help.  This is
        different from having crashed.  If the system has crashed, it
        has become totally non-functioning.  If the system is wedged,
        it is trying to do something but cannot make progress; it may
        be capable of doing a few things, but not be fully
        operational.  For example, a process may become wedged if it
        {deadlock}s with another (but not all instances of wedging are
        deadlocks).  See also {gronk}, {locked up}, {hosed}.  2. Often
        refers to humans suffering misconceptions.  "He's totally
        wedged - he's convinced that he can levitate through
        meditation."  3. [Unix] Specifically used to describe the
        state of a TTY left in a losing state by abort of a
        screen-oriented program or one that has messed with the line
        discipline in some obscure way.
     
        There is some dispute over the origin of this term.  It is
        usually thought to derive from a common description of
        recto-cranial inversion; however, it may actually have
        originated with older "hot-press" printing technology in which
        physical type elements were locked into type frames with
        wedges driven in by mallets.  Once this had been done, no
        changes in the typesetting for that page could be made.
