NASA got awesome mileage out of this vehicle... considerably more than was initially expected- over 7700 meters!
DAMN! Watch out Ford, you've got competition!

However, non-trivial disk acivity (such as compiling a port) caused the OS to shit itself with geometry errors.
That's my experience too, even with VBox 2.1.2-VBox 2.1.4: Any nontrivially intense disk activity will panic/oops the kernel with disk controller related errors. Once or twice it even was triggered in the installation phase when I elected to install some ports from the second CD. And forget about SCSI controller emulation as a workaround -- that instantly dies on newfs.
