Thanks, so it is the same problem, except that on Linux mmap fails
because large portions of address space have been reserved before
0x80000000, and on FreeBSD it fails because everything has been
reserved after 0x80000000.

I still would like to see this patch committed though, to fix bug
17718, but generally because the memory reservation doesn't fix
anything and only causes problems.
