I thought that was a transaction server like a MS COM+ Server. I think 
Linux has something similar. 

Maybe, the transaction processing of ADO.NET that rolls back transactions 
fits this bill.

Most database applications like MS SQL Server Oracle Sybase etc have 
transaction processing Commit and Rollback abilities.

And all of it can be used in a debugging process of a program needing to 
write transactions.

Why re-invent the wheel?
