It looks like we can turn off read/write access, but we can't turn it
back on. So,

mprotect (map->memory, map->size, PROT_NONE);
mprotect (map->memory, map->size, PROT_READ|PROT_WRITE);
leaves the memory with no access.

Eric saw this last week; I don't know whether he debugged into it
further.

Which repository is commit 1c12c4cf in?
