Definitely a binary search.

Well, it's currently broken on Solaris, and on some Linux distros
(RHEL3 for instance). The main problem is that we have to prevent the
kernel from allocating things above 0x80000000, but we still need to
be able to put things there ourselves, like Win9x native dlls. This
will require some restructuring of the memory management code.
