[cle-release-team] Kernel terracotta module?

[Cris J Holdorph]

It would be better to be moved to a special profile to not build by 
default.  I would not characterize it as dead, at least from the 
perspective of non-functional.  It did work.  You could characterize it 
as "not used" if you wish.

The page Seth pointed out really only describes one REALLY big problem 
that was not overcome.  That was with JSF component trees.  This problem 
only affects JSF tools.  Using Terracotta, individual tools have to be 
'terracotta enabled' on a per tool basis.  So this problem essentially 
means most JSF tools would not be terracotta-enabled or at least it 
would be difficult.

This functionality does give Sakai a very very slight answer to 
clustering/fail over.  If it's completely removed then we're back to no 
answer whatsoever.

I have personally experienced the Terracotta repos being missing, so I 
completely understand that problem in how it impacts builds.  I think 
moving the kernel-tim module out to a different profile will help with 
this problem while retaining the code.
