denial of service problem

[Jan Klod <janklodvan@xxxxxxxxx>]

Hello,

it's been some year now since I use loopAES (thanks to Jari!) and it's hard to 
complain. Still, there is one problem really bothering me when using my 
laptop: if some application is using encrypted disk IO intensively, it is 
even sometimes possible to reach a complete denial of service for ~10 min!!! 
For example, today I managed to achieve it just by starting video player and 
some terrible disk IO began for some reason (swap perhaps). I hate to 
reboot...
This might be my main security vulnerability now. 
The question I would like to ask: is there some way to balance system 
resources consumption such a way, I still have acceptable responsibility 
(access shell, lock session etc)?
It might be, I gave too little information, so I'd appreciate some questions 
or ready-usable advices! 

Apparently slow disk IO is the problem, but it IS caused by particular 
programs, which could possibly have much lower priority. It is terribly high 
now...

Have you experienced too slow reaction on session locking requests? What did 
you do?

Regards,
Jan
