--- Comment #166 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
jacob see #1066 reduce the mem block down to 1<<29 please

dmitry the return result is "-1" but is coming out at 0xffffffffff...

this is *possibly* due to using termux (proot). which would be a pisser.

i will have to fire up the laptop tomorrow (amd64).
