VirtualBox becomes Zombie process, requiring Host hard-reset — at Initial Version

Description
When installing several VMs in parallel, VBox processes may stuck.
Symptoms:
When this happens, all VBox processes becoming zombie processes without ability to get them killed. Windows Task manager did not help -- it refuses to kill VBox processes. I could not soft-restart or soft-shutdown host Windows either. Had to do hard-reset. When I press "kill task" in Task manager, the VM's GUI window disappears from Windows Desktop, but process continues to exist in Task Manager. (which I interpret as zombie process) Host OS & all apps continue to run, but becoming extremely slow, especially on Disk I/O operations.
Host: Windows XP SP2, Intel Core 2 Q6600 CPU, VBox 2.2.2. (VT-x enabled)
It happened with the following combos: (two VMs installed in parallel)
-Win2000 + Win 7 RC1 (32-bit)
-Fedora 9 and 10 (both 32-bit)
I don't see anything strange in VBox logs. But my understanding of them is imperfect.

VBox logs on Win7, F9, and F10.
