[K12OSN] Student Log-Ins Trashed

[Gideon Romm]

Mark, 

Next time this happens, prior to copying any files, issue the command:

pkill -u <username>

This will kill all processes owned by that user.  It sounds like some of
the files are not accessible because they are locked.  This typically
happens when you copy dirs while programs are still accessing them.
