dejagnu spawn & wait


Hi -

Indeed, the "close;wait" is not a perfect solution to the zombie stap
problem.  Systemtap catches SIGINT to cause an early exit, not
SIGTERM/SIGPIPE/etc, so dejagnu should send a SIGINT and wait a while
before the "close;wait".

By the way, I'm somewhat surprised that the zombie stap processes
should cause anything but an aesthetic problem.  They should consume
no resources except perhaps dejagnu file descriptors.
