Oh, caveat re: ps 'args' option:

http://pubs.opengroup.org/onlinepubs/9699919799/utilities/ps.html
args

    The command with all its arguments as a string. The implementation
    may truncate this value to the field width; it is
    implementation-defined whether any further truncation occurs.

I didn't hit any issues with a truncated command line, and I suspect the
length of sleep_argv0 is short enough it'd never hit such a truncation,
but I can't be certain.
