// pass null or just don't call this function, since it does nothing. This
// argv pointer will be cached so if you call this function again, you can pass
// null in the second call. This is to support the case where it's called once
// at startup, and later when a zygote is fork()ed. The later call doesn't have
// easy access to main's argv.
//
// On non-Mac Unix platforms, we exec ourselves from /proc/self/exe, but that
// makes the process name that shows up in "ps" etc. for the child processes
// show as "exe" instead of "chrome" or something reasonable. This function
// will try to fix it so the "effective" command line shows up instead.
