i think it's like this:
allocating it just ear marks it -- you don't actually, physically get
the memory when you allocate it. when you make use of it, that's when
things actually happen. so i think if you were to allocate 100mb of
memory not a lot happens, apart from you now have the right to use
100mb of memory. when and if you use, say just 1mb of that 100mb,
that's when things actually happen. that's when real memory (1mb) is
taken over by your app. it allocates on actual access/use -- puts
allocation off to the last possible moment basically i think.
Maybe you didn't notice that I said:
Note that VMTester does try to make the allocated memory be active by
writing and reading from it periodically.
oh right, sorry.
