[Cps4] tests statistic

[Florent Guillaume]

Note that in the context of CPS, all the nodes we'll use will be  
referenceable.


Some tests I'd be interested in having (but maybe reading the source  
would give an answer too) are the optimizations available for the  
following cases:

- can I get the number of subnodes of a node without taking too much  
time?
    For instance will the length of the NodeIterator returned by  
node.getNodes() be computed efficiently?

- can I ask the jcr:uuid of a node which has many properties without  
incurring the cost of reading all these properties.
   Zope will do that all the time.

- can I get the length of a STRING or BINARY value efficiently,  
without the value itself being read?
   This is important to be able to fetch in one go all the small  
properties, but make the big ones lazy.

BTW, I've put in
http://svn.nuxeo.org/trac/priv/file/nuxeo.capsule/trunk/src/nuxeo/ 
capsule/protocol.py
a first version of a simple protocol between Zope and the JCR.
I'll prototype it according to a simple text protocol (see doc/ 
PROTOCOL.txt) using a simple jython server.
