-  // The /proc filesystem does not provide any way to read “exe” links for
-  // pathnames longer than a page. See linux-4.4.27/fs/proc/base.c
-  // do_proc_readlink(), which allocates a single page to receive the path

-  // value, although neither is strictly a limit on the length of a pathname.
-  //
-  // On Android, the smaller of the page size and PATH_MAX actually does serve
-  // as an effective limit on the length of an executable’s pathname. See
-  // Android 7.0.0 bionic/linker/linker.cpp get_executable_path(), which aborts
-  // via __libc_fatal() if the “exe” link can’t be read into a PATH_MAX-sized
-  // buffer.
