The Jargon File (version 4.4.7, 29 Dec 2003):

wedged
 adj.

    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, hung (wedged is more severe than hung).

    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.
