I've uploaded some code that we've discussed and/or I think needs discussion  
to transaction/dev:
https://svn.boost.org/svn/boost/sandbox/transaction/dev/

it is not meant as an initial code base for "transaction", but only for this 
discussion.

basic_transaction_manager.hpp: my implementation of the TransactionManager 
concept

basic_transaction.hpp: the transaction scope class, and the atomic{}retry; 
macros.

transaction_manager.hpp: the (configurable) default transaction manager

basic_loc.hpp and loc.hpp: an example of a C++98 pseudo-template-alias. note 
the anonymous namespace and the conversion operators in loc.hpp. I think this 
technically violates the One Definition Rule but I don't think this actually 
causes a problem.

exception.hpp: defines isolation_exception, with some stuff to unwind 
the "nested transaction stack" up to the transaction that caused the 
isolation exception.
have a look at this, all of our libraries need an exception that is a request 
to the user to repeat the transaction, be it because of a MVCC failure or 
because of a deadlock.

I don't have wiki access. If this is connected to SVN please use my svn l/p.
