Ah yeah, I see. I was off by a power of two or so. 0xaab0000 is about
170MB. That's your current limit unless we initialize RVM to start above
the shared libraries.

Yeah, 0x50000000 could be a good choice, is also used by NetBSD 1.3/14
and FreeBSD. RVM stores the startaddress in the header of the RVM data
file during initialization and will always remap to that address.
