OOPS: 2.4.0-test10-pre6 around reiserfs 3.6.18

[Elmer Joandi]

under serious memory shortage, memory hog running and doing random access
over 133 MB(128MB ram) and disk output as fast as it could.
swap(128M) free = 0M, stable high disk io for long time, then
me killing X with -9 , got oops.
/home is on reiserfs, which is on raid, which has 5 slices all on same
disk (for fun).

     ^^^^^^^^^^^^^^^^^

Known problem. When you killed X, all shells wanted to update the
.bash_history (or .history) file at the same time, which triggered the
bug.

                                           ^^^^^^^^^^^^^^^^^^^^
Yes, this looks like the symptom.

This was fixed in 2.4.0-test10-pre7, please upgrade to 2.4.0-test10
(final version) and see if it fixed your problem.
