Another data point - the OS in the VM in question hanged today

Judging by the last seen timestamp, the machine should have been in
the process of receiving rsync backups - so IO-bound.
It looks like something really could be fishy in this area, at least
with VMWare. The same thing happened again, and I have an additional
data point: I left 'top' running on the console and when I attached the
VMWare console to the VM, the top was still running ok, but as soon as I
hit a key on the keyboard, the OS console locked up. All other symptoms
were as I enumerated above.
A buildworld is enough to kill the console for me under QEMU on a slow
Windows host. Never seen problems with a native install of FreeBSD, though.
