Yet another way to run a sub-process in pop11

The library LIB ved_clock, described in HELP ved_clock can be used
in Ved to create a digital clock that shows the time on Ved's status
line. The clock runs in parallel with everything else. To see the
code (originally due to Roger Evans) see LIB VED_CLOCK

It uses the mechanism described in HELP POP_TIMEOUT as well as the
vedprocesstrap mechanism described in REF vedprocs.

The latter makes the clock work while you are typing, by grabbing
some of the interaction during Ved's processing.

The former works if you do nothing, to ensure that the clock goes on
running while Ved is waiting for you to type something.
