:> The problem with that 92K of data space is that it contains

:You might want to check this, actually. How much statically initialised
:data is there in libc? Not much. 8) You may touch a lot of that 92k,
:but you're not going to COW very much at all, so you still get the LOR
:benefits.
As far as I can tell, Mike, *I* am the *ONLY* one posting actual
test results on this topic. Maybe you should run your own tests
rather then just assuming I am wrong and telling me to run more.
