I never meant to actually *publish* large object support without 
mechanisms ensuring consistency in place. Yet I would prefer to have 
most of the other issues - what should the official API's first 
iteration look like?, is the approach I've taken so far basically sane? 
and so forth - sorted before moving on to the more complicated aspects. 
So far, it took some time to get used to the code base and acquire 
*some* knowledge about INFINISPAN's inner workings, but it hasn't been 
exactly rocket science. Just a lot of work. Ensuring consistency, 
however, won't probably be that easy. Especially since I only have a 
very shallow understanding of INFINISPAN's transaction support's inner 
workings.
