Arnd,
The EXIT bit in the status register is not sticky.  It is only set while
the SPU is going through the EXIT steps (i.e. the hardware erases
all of LS and the register file, and then "unlocks" the LS).
An alternative is the IS bit (the isolated bit) which tells you 
whether the SPU is isolated or not.
It is still not clear to me how your change bubbles up to the user.
It seems you're making assumption on the state of the SPU 
based on whether the application has completed or asked for a 
second app to be brought in....?
Best regards,
Kanna
