I'm still using the `mac_mmap()` wrapper in `map_file_into_view()`, but for `map_pe_header()` I found that macOS doesn't restrict executable mapping of files on noexec filesystems. Was detecting that the only reason `map_pe_header()` uses `PROT_EXEC`? If so, I'm only doing RW mapping there on macOS.
