The problem is, it did not the right, at least according to the
comments:
/* we require comm to match and to not be truncated */
/* in Linux, if comm is 15 chars, it may be a truncated
* name, so we don't allow that to match */
The old version checks only the comm value (part of /proc/$pid/stat) which is
restricted to 15 characters:

The current variant uses argv[0] as match.

Looks like a feature request.
