There is, but:

1. The process would be killed, here the call will just be ignored.

2. There may be other side-effects when you change the prg-flags of the  
app.

It is Setexc, not Ssystem (been too long when I implemented this). Ssystem  
is used to change the behaviour of Setexc.

There will be another patch for XaAES where it can be activated by XaAES  
so any dirty prgs run before XaAES won't be affected.
