inodes and soft update

While trying to improve one of the tests from the kernel stress suite,
I have run into a strange problem. The program tries to use 90% of the
available inodes on a file system. This works fine where "soft update"
is disabled. However, when enabled I seem to run out of some resource
and the file system winds up corrupted (/tmp: unmount pending error:
blocks 0 files -83).
