For the present Gnus code, it starts the timer when Gnus detects
that the external viewer process exits.  And after one minute,
Gnus tries to delete a data file.  So, the file should not be
deleted while the viewer is running (if not, it's a bug).
Nevertheless does it cause a problem?

However, if eog is launched by way of xdg-open and the like, Gnus
immediately detects that the process of xdg-open, not eog, does
exit, and starts the timer.  In that case, Gnus doesn't know
whether a viewer is still running, and the viewing will fail, if
it is eog, one minute after.  But the solution for this is obvious.
That is to configure the mailcap so as to use a viewer program
directly, rather than to launch a viewer by way of xdg-open.

I'm going to try eog anyway in this weekend.
