Hi Mike,
Yes this is still an issue, I have attached strace output for the same test
case in one run it passes and in the other it fails.
This test was run on a fc-6 machine.
[EMAIL PROTECTED] fs_perms]# uname -r
2.6.18-1.2798.fc6
[EMAIL PROTECTED] fs_perms]#
Thanks,
Praveen

are you still having problems ? if so, it'd be useful to have strace's to
compare the failing case against the passing case.
