Well, that's what I thought.

I must admit I'm not really comfortable with this interface. IMO it would
be better if _open() created the suspend blocker giving it a name based on
the name of the process that called it. Something like
"<process name>_<timestamp>" might work at first sight.

Alternatively, "<process_name><number>", where <number> is 0 for the first
suspend blocker created by the given process, 1 for the second one etc., also
seems to be doable.
