readonly mmap maps true
OS protected readonly memory and does not update the underlying file.
When python detects and attempt
to write a readonly mmap, an exception is raised; Is there an obvious
choice for what the exception class should be?
I need to re-submit the patch for a few stylistic issues anyway, and
would like to fix this while I'm at it. Right now, the
patch raises ValueError. SystemError and RuntimeError also come to
