[QGIS-Developer] sudden performance issues with my QGIS installation

[Nathan Woodrow]

I think it would better spent looking into why and fixing that and not just
bidding it and removing quite good feature we want people to use if we
can.  The browser is quite powerful and bidding it by default would be a
bit of a shame.

Suspect we might just have to get creative with how to handle the file
loading, they should already be done in background threads but maybe
something more is needed
