                * thread.h (struct exception_page): Make mode bits a union 
thereby
                providing straightforward access to the raw bits.  Add field 
crc.

                * exceptions.c (crc) [! NDEBUG]: New function.
                (exception_handler_activated) [! NDEBUG]: After saving the frame
                state, calculate the crc of the header.  Check it before
                returning.
        
                (exception_frame_slab_alloc): Save the UTCB state before calling
                storage_alloc and restore it before returning.
        
                (exception_handler_activated): Assert that
                EXCEPTION_PAGE->ACTIVATED_MODE is set.
        
                (exception_handler_normal): If we fail to handle the fault, 
panic.
                (exception_handler_activated): Likewise.
        
                * ia32-exception-entry.S (_exception_handler_entry): Correctly
                test and set the flags.
