Donald Buczek dixit:

> To be fair, this daemon doesn't use /proc/pid/stat for that, but /proc/pid/comm

Yes, and that’s proper. The field in /proc/pid/stat is size-limited
and so not necessarily distinct.

> As /proc/pid/stat is also used in many places, it could as well use

> other source.

No, because the data in /stat is incomplete *and* anything using
it that would be affected by escaping was already broken.
