 See diagnosis at comment:15:ticket:21648 .  Now that worker threads can
 malloc a bit more, they can need to mprotect(...PROT_WRITE) larger chunks.
 This requires an increase in MALLOC_MP_LIM.

 In the longer term, we should replace our sandbox's string-interning hack
 with a privileged helper hack.
