Subject: [PATCH] Make the unit test work on systems without mmap(). This is
 required for, among others, Windows support. For Windows in specific, we
 could have used CreateFileMapping/MapViewOfFile, but this should at least get
 us a bit closer to compiling, and is of course also relevant for embedded
 systems with no MMU.
