I wrote the pc-page-writeable and sp-not-MAP_STACK code to be shared, and
then ran into the messaging being poor. Then I fixed the messages. But
there are two sub-cases of sp-not-MAP_STACK -- one at syscall time, and
another at regular userland trap (on some architectures), and I bungled
that messaging. Correct that now, while I look for yet another better way...
discovered by millert, who ran an pre-MAP_STACK binary.
