     56 # malloc(), instead of custom allocators. Note that the host process must
     57 # reside at low address, as heap which grows upwards directly follows it.

     59 # This means disabling ASLR on windows and linux. If no suitable memory layout
     60 # is detected, LJX will switch to the original, more controllable 2GB allocator.
