When evince is already displaying some document, it will, when
called as "evince document" return quickly and instruct the
running instance of evince to open the given document. This
sometimes interacts badly with scripts that delete the document
right after evince has returned.

It would be good to make evince wait until the other instance
has opened the document (un)successfully and return an status
code indicating this condition to ease integration into scripts
that display documents.

Alternatively, a --disable-factory option like gnome-terminal
has could be added for such use cases although the former is
IMHO much preferable.
