Just noticed that my understanding of memory management on Linux was too 
naive (didn't realise that in all those years of administering servers - 
D'oh!). Limiting the data segment won't help as larger allocations will 
use mmap() instead of brk().
Seems like there's no simple solution currently. :-/

FUp2 security, I'd guess.
