about this... if one of my programs goes a bit mad and tries to write
to something it shouldn't, does the memory write actually take place?
or does Linux realise before and kill the process?
it creates a page fault because the memory wanted won't currently be in
physical ram, Linux would go and fetch this page (if it exists), realise
that the process doesn't have rights to access this page and send a SIGSEGV
to the process. process then drops dead, creates a corefile and the user
goes 'huh?... oh, missed the flipping & in my scanf'
[is that right?]
