Comments :
1. file /dev/zero seems to be deleted after running runalltests.sh, this is being investigated.
2. ftruncate03 is not cleaning up directories in /tmp properly, this has been fixed in the CVS tree.
3. Bugzilla #264 description - shmdt system call does not fail on unshared memory segments.
4. Bugzilla #266 description - personality system call does not fail when expected.
