VM locks up under heavy disk activity

Description
Since Virtualbox 3.0 I (and another user I know) have experienced semi-repeatable lockups of our Virtualbox VMs when the guest OS tries to do a lot of disk I/O.
The symptoms are that the guest display stops updating; though the mouse still moves, it does not respond to clicks (we're using the guest additions though so I guess the mouse moving does not really mean anything). The guest kernel responds to low level networking stuff, enough to return a 'connection refused' message to the host when I try to SSH in to see what's going on.
I haven't reported this until now because it is not possible to trigger this bug reliably, and the guest's log file doesn't contain anything useful; however I ran into it five times in as many days in the following circumstances:
- Run 'wineboot' from wine 1.3.9 (creates ~/.wine, containing a lot of small files ~/.wine)
- Run 'git merge' with a sufficiently complex merge
- Copy a lot of files to a vboxsf shared folder on the host
Over the months I have tried tweaking various guest settings, such as enabling/disabling the virtual disk controller cache, trying a PATA virtual disk controller rather than SATA, etc) but no existing open seems to make a difference.
My host is Windows 7 on amd64, and my guest is Debian GNU/Linux using 2.6.32.
