I have a trace that has quite a few Expert Infos: there are about 61,000
packets and 17,000 Expert Infos.  (I'll try to find a--or find a way to build
a--similar trace from the public menagerie.)

In the Gtk UI opening the Expert Infos dialog has a slight pause but it still
opens in less than 1 second.

In the Qt UI it takes ~36 seconds to load the Expert Info dialog.  A progress
bar shows up in the lower-left corner while this is happening (which is good
given how long it takes) but it *appears* (I could be wrong here) that the
progress slows down as it gets closer to being finished (linear insertion
somewhere?).
