Follow-ups

--- Graf Yang 2009-10-12 05:44:58

The reason of access02's crash is because of mmap failed,

chown0X's crash seems have different reasons.

--- Graf Yang 2009-10-15 23:21:53

Fixed after apply upstream patch 239e40d..0583f16

chown0x/fchxxx test also pass with properly set their permissions.
