I cryed ... hit my head at the wall and cryed again.
Why ?

1. Started thinking WHY it leaves files and folders to their places ?
2. Why doesn't it work by the battern ? Sometimes erases one things and 
sometimes does not ?
3. Why it needs more rm commands than the old system !?

So with my stupid head an "no-ideas" thinking I wrote in some sleep 
rm -rf /home/terminal9/*
sleep 2
rm - rf /home/terminal9/.*
sleep 2
rm -rf /home/terminal9
sleep 4

tar command
what happened ? All the directories were erased !! For god sake.
Now I had a working script but logout took place for 8 + 1 seconds. Not 
nice. What about if I change first two sleep intervals to 1 second and leave 
the last one as is ? So logout should last about 6 seconds. It was faster 
and like usual ... no success. Folders and files made by the user were NOT 
erased :'(

cryed some more

So I was thinking that I need a break and went to make some coffe. When I 
returned, changed the intrervals back to values that worked, logged in, made 
some foldest and files, logged out again ... logged in and ... NOT ERASED 
!!! :'(

So the intervals were the same as these that worked last time but now they 
do not work. This is weird and unusual problem. What's going one ? My server 
has been changed to super-server that works so fast that scripts are unable 
to follow it !?  This just makes me cry ... :(

Does anyone have more ideas what to change/try/eliminate ?
