I am just being defensive here. I know that _at least_ Microsoft's compiler
has a problem, but it might also be present in other compiler and
architectures -- it is more a problem of the binary format than of the
compiler, I believe.

It uses mmap where available, but I am not sure the flags are the right ones
all the time. Another advantage is that this memory is totally free after
use, unlike static data in a compiled file.
