This is a 1.3.1_XX only bug.
VolanoMark hang with 1.3.1_09(b01 and b02), the problem was caused by a putback of bug fix, 4805573, which is a partial fix of 4526887. After removeal of this bug fix from 1.3.1_09, the hang problem no longer exist.
Another bug fix, 4873131 which was integrated into 1.3.1_10, completed the whole fix of 4526887, so the hang problem with VolanoMark goes away. But it still hangs with other problem --- malloc dead lock with asynchronous signals. this bug filed for tracking this problem.
