I agree that it would be good to allow the app in user space to handle the 
syscall.  The problem is that there are several syscall that NEVER return.  

The work to make sure that these syscalls return gracefully with the 
appropriate errorcodes is going to take some work.  The patch I propose is an 
interim solution that at least keeps the CPU from being hogged.
