Not only is a problem that deleting a bucket costs money, but if you have a big bucket with many deeply nested files, it can take a really long time to clean it up using the AWS command line.

I ran into this with a bucket full of EMR log files a few years ago and had to figure out some pretty crazy command line hackiness, plus running on a EC2 machine with lots of cores to figure it out. This a write-up I did if anyone else ever runs into this issue.
