I certainly knew that a RH9 glibc in the client can trigger the vsyscall segfault hang, but it only happens if the /lib/tls libraries are present; presumably the same code is present but it moved from the tls only code to the general code for the FC1 glibc. This is why I originally thought it was an issue with tls and suggested hiding the /lib/tls libraries. I think the fix works in both cases.

Actually, I am wrong, the fix doesn't work with a RH9 image, which still crashes, though the workaround of hiding /lib/tls in the image does work in this case.
