Reorganizing the address space

There's a difference between non-portable and broken. For example, I've used the mmap start address specification to do emulation and testing (on my desktop machine) of a flash filesystem that would run on an embedded device (and that was located at a certain address on that device). While the mmap call wasn't guaranteed to work, it did, and saved me a few weeks of effort re-writing the filesystem.

If this change broke my program (it didn't) I wouldn't have cause to yell too loud; it was not guaranteed to continue to work. But I still wouldn't call the program "broken".
