Gene, what did top and iotop show? When one of my machines gums up, it's always been due to the expected disk or cpu thrashing. One culprit was firefox hogging cpu insanely on one particular website, another was jpg to ps conversion of a document scan using 97% cpu for a remarkable amount of time. If you're updating a lot of stuff, then the package install scripts could hammer the cpu quite a bit before the next package can be digested. If hundreds of MB also need to be written to disk, the traffic jam just worsens. (OK, you know that ... but top and iotop are good for easing paranoia, I've found.) One way to remove the concern could be to just fetch the packages (apt-get --download-only), then install them after disconnecting the outside world. (I tend to use dpkg for that, but that's just habit.)
