Insight session regression (?)

[Tom Tromey <tromey at redhat dot com>]

I started Insight like this:

    gdb /my/executable

Then I set things up and did some debugging.
Finally I exited.

Then I re-ran the same gdb command line.
Of course it just comes up in the default mode.
If I then select /my/executable from the File menu, I expect it to use
my old session.  However, it doesn't -- my old session is wiped out.

I think this might be a regression, but I am not certain.
In any case I found this surprising.
FWIW I think "gdb /my/executable" should really reload my session by
default.
