Ticket #6429 (new defect)
Closing Vbox and save the guest state reaches 97-99% and hung forever (I killed it after 10 minutes or so.)

Guest: GNU Debian/Linux (32bit) Host: Windows XP SP3 (32bit) VBOX Version: 3.1.4 r57640
When I tried to save the running state by clicking on "[x]" button on the upper right corner of VirtualBox, VBox started to save the state (after I click save the virtual machine state), but after reaching 99%, it didn't proceed any longer. And the remaining time shown was initially about 10 seconds, but then grew longer and longer until I killed it after about 10 minutes of non-activity. (I checked using windows task manager and performance monitor that no CPU was used by Vbox, and no disk I/O was taking place.)
Additional Info: A suspect. VBox driver for clipboard sharing hung?
The reason I wanted to shut down XP host was that somehow for some reason, XP programs began complaining that it could not clear clip buffer(??) and pasting began failing everywhere. Initially I thought the paste problem was only with guest-to-host, and host-to-guest, but as it turned out inter-program pasting between host win XP programs failed(!). So I could not copy a paragraph in ThunderBird browser on win XP host to MS Word program on win XP host.
So I thought something was fishy with win XP host, and decided to reboot XP anyway although the hung Vbox window was still present.
But during the shutdown attempt, a service named (SORRY I FAILED to take note of the name !) *VBOX*Clip*Share* something service could not be stopped. (A dialog popped up that it waited for the service to stop, and obviously it was not stopping. When I hit [terminate], then the dialog disappeared as well as the background hung Vbox(!), too (the greyed out window of Vbox which was staying on the background disappeared, too!)
I noticed there are clipboard related problems:
ticket # 417 Shared clipboard does not work and also affect other programs
seems to be very like the problem I experienced.
The latest ones are: ticket 6150 Bidirectional Clipboard copy stops working eventually, Win client to Fedora host, then both ways. ticket 6091 Paste into windows guest from linux host hangs ticket 5266 Shared Clipboard stops working
But I am not sure if they are related to my particular hung problem.
Log is attached.
