Poor (or non) performance when moving features

QGIS 2.4 and master exhibit extremely poor performance (or total failure) when moving a moderate number of features in edit mode. I have tested with 5,000 random points:
1. load the layer (both shapefile and memory layer were tested)
2. enter edit mode
3. select a lot of features (~5,000)
4. zoom out
5. move the selected block to a new location
In my testing on Windows, Mac, and Linux, this process takes longer than I am willing to wait and in fact may never finish.
Currently I have a move attempt that is 15 minute and counting with QGIS locked up and the CPU usage at 99% (Linux, QGIS master).
To duplicate you can use the Vector->Random Points feature to create a test layer.
