Thanks Scott. It didn't occur to me to try switching my instance to small,
do the install, and then switch back to micro. I'll give that a try.

Also, for some reason I thought the amd64 builds of Ubuntu were lacking in
some components. Maybe that's only true for client, but I definitely saw a
recommendation somewhere to use i386 unless there was a real need for > 4GB
of memory.

t1.micro instance hangs when installing sun java

Bug description:
Binary package hint: cloud-init

I booted the 32bit EBS lucid AMI (ami-1234de7b) for a t1.micro instance. I attempted to install Sun Java. The instance hung during the install. Repros every time. Only repros on t1.micro instances. I tried adding swap in case it was an out-of-memory condition, and it still repro'd. No reboots or anything else like that were involved so it's not the same issue as #634102
