Summary	0008635: Opening or resizing region list in a large session makes Ardour unresponsive for a good while
Description	The Locations panel or window are very slow to open up or resize. Once they do chug through that, they work relatively fine, but using them in a large session (>100 ranges) takes minutes of time to just get the panel or window ready. I attach a screenshot of a window that was maximized and then took a dozen seconds (or more, not sure) to refresh.
