* The reason we can't do this for Flash player-based apps is that unlike
* AIR apps, the process that we launched sometimes acts as just sort of a
* "launcher" process that terminates quickly, and the actual Flash player
* is in some other process. For example, on Mac, we often invoke the "open"
* program to open a web browser; and on Windows, if you launch firefox.exe
* but it detects that there is already a running instance of firefox.exe,
* the new instance will just pass a message to the old instance, and then
* the new instance will terminate.
*
* @param pl
* a process listener, or <code>null</code>
* @return true if pl refers to an AIR app that has terminated.
