This may need to fall under another bug report:
Today I booted into recovery mode to recover some data from a failed drive, then resumed the normal boot into a console. I then moved a large number of files from one drive to another. During the transfer I thought that the system was acting sluggish so I switched to console 2 and started htop. Htop showed that all of my memory (4g) was in use and my swap was pretty much full (994/996M.)

using df I saw that /var/lib/ureadahead/debugfs was listed so apparently ureadahead was profiling my actions while in single user mode.

Maybe ureadahead should not run in single mode.
