Are you sure this is true? The problem seems to be caused by the
"why" tab in the lower pane, and that code exists in 4.x too. Anyway,
the fix is to do at least one of
(1) Only run "why" if that tab is shown;
(2) Run "why" in a background thread and post its results when it
finishes;
(3) Find out why "why" is slow on certain packages (lots of rev-deps,
perhaps?) and make it faster.
I think (2) is actually the ideal solution: even with (3), it's
unlikely the calculation will always be so fast as to have no lag.
(1) might be a reasonable stopgap, but the problem would come back
if you ever looked at that tab.
