Do you have a test case to reproduce the errors?

I see that we call msync followed by munmap, neither one checked.

No, I don't know how to provoke such an error other than passing illegal parameters..(or munmap'ing the mmap'ed area).

msync() is only called in mmap.flush() and it is checked for an error.
