Solved. This was scheduler bug fixed in 2.6.35, but I used 2.6.34.
This is really funny. This bug (PF_STARTING lockup) was found and
fixed by me & Peter.
Oh. But I hit yet another problem, BUG_ON() in __utrace_engine_release().
Again, it is not reproducible, I saw it only once in dmesg and I do
not even know for sure what I was doing.
I'll contiue tomorrow, but if I won't be able to quickly resolve
this problem I am going to ignore it for now. This time I think
ugdb is wrong.
