I'm not using nautilus, but I'm still affected. I'm having a system slowdown even when copying files over 10Mbit network, so it may be not just USB related. Generally, when some I/O is at its full capacity (being that slow USB 2.0 or slow 10Mbit network transfer), the whole I/O of the OS comes to a crawl. For example, if I copy a 1GB file over 10Mbit network, until that copying is finished, everything disk-related is slowed down (stating of programs, opening files). I have 3 hard drives in my computer, if I copy something from second to third (OS is installed on first), starting programs is still slowed down, although drive holding the OS and programs isn't participating in file copying.
