New Revision: 56282
URL: http://svn.boost.org/trac/boost/changeset/56282

Log:
Fixed crash bug with read-only transactions inside of deferred_update commit 
where the in-flight transaction lock was released before scanning other 
in-flight transactions. This caused a crash in the event another transaction
was put into flight while scanning the in-flight transaction set.
