hung
["hung up"] Equivalent to {wedged}, but more common at Unix/C
sites. Not generally used of people. Synonym 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.
