Most of the non-x86 ports seem to have similiar limits.

Hm. 32bit Mips has 2GB user process space. The stack grows downward
from 0x7fffffff, the space from 0x2a000000 upwards is used for shared
libraries, executables load text at 0x00400000, and data at 0x10000000.

Using the space between 0x30000000 and 0x70000000 might work, I'll give
it a try.
