Description of problem:
This is a follow-up to bug 1149624. UsbDk part of that bug is fixed but remote-viewer still can e.g. eat 100 % cpu
Version-Release number of selected component (if applicable):
win 7 64b
tools 3.6-6: mingw-virt-viewer 2.0.8, usbdk 1.0-10
Steps to Reproduce:
1. unplug usb device while redirected
2. wait (or continue working with VM)
virt-viewer process may get to 100 % cpu not reacting to any input or it may just stay around
virt-viewer continues running and exits cleanly when told to do so
