I'm pretty sure the code doesn't work in the general case with a
fragmented memory map. It attempts to do a linear scan, but it
only performs a single retry.
Please refactor this to use the already existing code for mmap()
allocation hinting. This already includes a special case for a
near-exhaustive linear scan.

You can find out by looking at the header of any binary on the
target OS.
