My understanding was that the kernel was going to do something nasty 
like terminate your application if it tried to write and found a 
write-protected page? If all that happens is that the page doesn't get 
dirtied, I agree that it isn't likely to be a problem otherwise since 
the kernel probibly isn't going to write pointers anywhere (certainly 
not pointers to heap objects).
