yes, this is how apps are handled on the phone. an app that goes to
background recieves SIGSTOP by the system, only system services
(media-hub for example, so your music plays on if the music app is not
in focus) keep running ... since the shell in which you run
mirscreencast is a child of the terminal app it gets suspended
alongside, this is a (security and powermanagement) feature, not a
bug ...

mirscreencast would have to provide i.e. a dbus service you can just
trigger from the terminal (but not actually run directly from the
embedded shell, dbus would run it) so that it operates in background ...
