Transactions are supported by the DBUS protocol, it's up to the binding to 
expose it to the application.

It allows asynchronous processing of requests which tends to be handy in 
service providers such as a DConf daemon.

The main dependency is libICE, the rest is pulled in because of Qt. I believe 
Maks Orlovich wrote an implementation with its own ICE implementation. I am 
not sure if it is actually maintained or whether it has been released in some 
way though.
