C# Class Shielded.CommitContinuation

An object used to commit a transaction at a later time, or from another thread. Returned by Shield.RunToCommit. The transaction has been checked, and is OK to commit. This class is thread-safe - it makes sure only one thread can initiate a commit, but any number of threads may try a rollback in parallel.
