I think they are different. IMO, performance improvement is the time
or memory reduction to some degree. This kind of change can be user
visible (10 min -> 10s) and can be user invisible (2s -> 1s).
There already is a level of interruptability, the only change is in degree
of responsiveness.
We*can* start adding such things to NEWS, but we don't do so today.
Before we start imposing this on everyone, we'll need to establish
what does and does not qualify - I'm guessing we don't want to add
a NEWS entry for every little performance improvement.
However, this change isn't performance improvement, because it doesn't
shorten the time of operation like "b 'foo.c':bar". This change only
makes GDB more interruptable during some operations, IMO this is a good
news to users and we should let them know.
Regarding to NEWS entry for performance improvement, I don't have an
opinion on it.
