Chances are this bug does not exist anymore. Robert Watson rewrote a large
amount of the pipe code to improve its locking and security, and I hammered
out some left-over bugs that showed up with SMP testing. Please try either
upgrading to -CURRENT or, if you are not using MAC, these two diffs might be
all you need:
