There isn't a fork, but there is a method built in that is rather similar to
the alarm(2) interface in the kernel, which is called Absolute Timeout.  The
method of using this is Set(TIMEOUT(absolute)=30), which sets a timer that
will fire in 30 seconds.  When that timer fires, any application that is
currently executing will terminate, and you will be redirected to the "T"
extension in the current context.  Note that you can also cancel this timer
by using setting the timeout to 0, i.e. Set(TIMEOUT(absolute)=0).

Also note that there can only be a single absolute timeout per channel (i.e.
setting a new timeout resets any timer currently in effect).
