ok, if there's no need to special-case stack mappings, then we shouldn't
do so.  it would just be extra complexity for no benefit.

from UVM's standpoint, there's no real difference between the initial stack
for a process and any other amap-backed mapping.  other pthreads will have
their own stacks, and we don't want to treat all of those specially,
so we shouldn't treat the initial stack specially either.
