commit 776c41ab3c82884e32875b6150f98dafccfa2a82
Author: Phillip Susi <psusi ubuntu com>
Date: Sun Jan 20 10:33:54 2013 -0500
Thread the internal copy algorithm (#685740)
Have the copy code create a background thread to do the actual copying so
that it won't block the main loop.
Part of Bug 685740 - Refactor to use asynchronous command execution
