it was hard to catch such a thread as i have to be logged on when it appears and
start the strace. otherwise it's very hard to work on the machine when it has a
huge load. anyway here is the strace output:

--- strace -p 30610
[...unforutnately it is not from begin on my screen buffer wasn't that huge...]
