I'm using a Dell Mini 12, which is a dual-core
Intel(R) Atom(TM) CPU Z530   @ 1.60GHz (which often
throttles down to 800MHz), with 1 GB RAM.  I
was seeing something that was taking a very long time,
which seemed a lot more like timing out attempting to
access a resource rather than any difficulty crunching
data.

Bug description:
Binary package hint: ecryptfs-utils

I have the encrypted ~/Private enabled. In /etc/pam.d/common-auth is the line:
auth    optional    pam_encryptfs.so unwrap

If that line is commented out, then doing something like 'sudo ls' is instantanious after I enter my password. 

If that line is not commented out (like normal), 'sudo ls', or anything else involving my password such as logging in, and unlocking the screensaver take about 4 or 5 seconds longer than they need to.

The following is also syslogged. I'm not sure if it's relevant or not, but that 5 second delay seems to be the pause that occurs.

This doesn't seem to impair the functionality, but it is a little bit annoying.
