Could we have the 2arg vs 3arg msync issue here? We have a define called
HAVE_MSYNC_3_ARG in there that I remember having problems with a long time
ago. I notice that the spots that use msync() in addition to not checking
MMAP_NEED_MSYNC don't check HAVE_MSYNC_3_ARG either.
I doubt its the case but could OSX be a 2arg msync variant BSD? :-)
