:hung: [from `hung up'] adj. Equivalent to {wedged}, but more
common at UNIX/C sites. Not generally used of people. Syn. with
{locked up}, {wedged}; compare {hosed}. See also {hang}.
A hung state is distinguished from {crash}ed or {down}, where the
program or system is also unusable but because it is not running
rather than because it is waiting for something. However, the
recovery from both situations is often the same.
