This seems to be a rather platform dependent thing.  On HP-UX, the
MAP_VARIABLE option tells mmap() to choose the memory location itself.
The man page on HP-UX advises to explicitly use either MAP_FIXED or
MAP_VARIABLE (for forwards compatibility), but it seems that
MAP_VARIABLE is default if neither flag is used.

I should probably tweak the runtime to pass MAP_VARIABLE on HP-UX.
