Except when using SysUIAppLaunch, you never have two programs running at
once. Your program gets an appStopEvent and shuts down, then the
application you launched starts up. That's one reason why the parameter
block you send to the new app can't be owned by your original application --
it isn't there anymore when the new app processes it.

Using SysAppLaunch lets you do this, but the second app is not guaranteed to
have globals -- in fact, it will only have globals if you call yourself.
