###@###.### 2003-12-18

We installed glibc-2.3.2-27.9.7 and unset LD_ASSUME_KERNEL.
And the problem starts to occur.

This problem is most likely caused by a race between
pthread_cond_wait() and pthread_cond_signal() on RH-9 with NPTL.

We will set up AS-3 and retest. Will update the bug report with
the status on AS-3 box.

The problem is not reproducible on AS-3 box. That proves Hui's theory
that the bug is in RedHat 9's kernel.
