 // Pass in the argv from main(). On Windows, where there is no argv, you can
 // 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.
