After rerunning my test case a few times with exactly the same configuration I was unable to reproduce neither a filesystem corruption nor a allocation failure. Your patch seems to fix the issue.
Sorry for the false negative!
BTW: This is my test case: tar xvf linux-2.6.36-rc7.tar.bz2 && rm linux-2.6.36-rc7.tar.bz2 && tar cvf linux-2.6.36-rc7.tar.bz2 linux-2.6.36-rc7/ && rm -rf linux-2.6.36-rc7/ Any big tar archive will do the job...
Thanks, //richard
