Jazz SCM: Local Sandboxes in AFS

We have developers on Linux that would like to place their local
sandboxes in the Andrew File System (AFS). They are doing this because
their development and test work is performed on different machines. AFS
does not support all the lock semantics of a native Linux filesystem,
notably byte range locking.

Does the Jazz SCM client perform byte range locking? I have seen the
tech article discussing using NFS and its emphasis of configuring NFS to
support locking. I believe NFS supports byte range locking which allows
it to work with the Jazz SCM. We have users seeing strange results with
pending changes and the workspace going out of sync. I suspect it may be
related to locking. Are my suspicions unfounded?

Thank you,
