kepler hangs when home directory is on an NFS mount
When I start kepler.sh in a freshly unzipped kepler distribution, the process hangs on the splash screen.
Investigating the state of Java shows it is hanging in a 'futex' system call.
This happens when the home directory is on an NFS mount; it doesn't happen for a user with a home directory on the local disk.
This is the case both for Sun Java 1.4.2_12 and 1.5.0_08.
The systems that (so far) show this behaviour: Scientific Linux 3.0.7 and CentOS 3.8.
