During execution of that handler, it make sense to prohibit the 
allocation of any GC memory, and prohibit the throwing of any 
exceptions. I presume that's why they're there (??)

@system is default

(btw, change -1 to 1 in the exit function, i.e. -1 is not valid, 
0..255 is valid.. but some of those you should avoid using).
