You can attach gdb to the VM and then call printAllStacks().

Similar features appeared years later, I suspect unrelated to my efforts.  What I did was hack the VM such that the dump (on the vm menu) gave all (non-dead IIRC) processes rather than just that for the active process; for it to be readable required some changes to when the dump adds a line feed.
