This command is implemented by activating an alarm at procedure
entry. If the timer expires before the goal completes, the alarm will
through an exception @var{timeout}.
throw an exception @var{timeout}.
One should note that @code{time_out/3} is not reentrant, that is, a goal
called from @code{time_out} should never itself call
@t{time_out}. Moreover, @code{time_out/3} will deactivate any previous
@code{time_out/3}. Moreover, @code{time_out/3} will deactivate any previous
alarms set by @code{alarm/3} and vice-versa, hence only one of these
calls should be used in a program.
