There are two replies here. First of all, if you're running in a sandbox
there are some kinds of features you just can't get, and its something
we have to accept. For instance, a sandboxed gedit can't really have a
file selector sidebar. This is just a fact of life, and our goal is to
make the sandboxing APIs good enough that this does not hurt your
everyday use.
Secondly, this specific case. Monitoring is just a more efficient way of
polling, so, i think it makes a lot of sense for the system to allow
monitoring as a feature, and to have its permissions be keyed of if the
app has the permissions to do a polling version of the monitor.
So, the question becomes one of: If I've opened or written the latest
version of a file, and then some *other* app creates a new version of
it. Am I allowed to read/write that version?
I believe that we should at least allow reading it, as that is a not
something i think would surprise most users. Allow writing to the new
file without reading the old one first could risk losing data, so we
should perhaps open a dialog warning about that. On the other hand, in
the gedit case above that would cause two warnings about the same thing.
