the top level per-process page table on arm has to be a 16kb
contiguous chunk of memory.  if you don't have 4 contiguous free
pages, the pmap gets unhappy.

Sometimes killing processes will free up enough space to recover from
this, but over time, some workloads tend to induce death from
fragmentation..
