AFAIK the GUI is not suspended. This behaviour is relatively new, I 
don't remember when it started. It affects multimedia.

      You can run a long job, like a backup script, and it
      should continue running non stop when switching to a TTY.

The same toolset that is used to "detect who is at the seat" does it. 
Rationale is that it gives permissions to use the sound device to the 
person that is seated, meaning the person having the GUI. As when in tty 
mode no one has the GUI, there is no permission to use sound and things 
stop.

This could be HAL/ConsoleKit/PolicyKit. Or could be the display manager 
doing it.

The way to avoid this is not using the TTY, but an xterm.
