Description Andrew Bartlett 2014-05-02 07:56:34 UTC
If an event fires during an LDB transaction, an unrelated operation can occur during the transaction, and if the transaction were to be cancelled, there would be a silent rollback (despite the client having been indicated success).  Additionally, other processes could be called via IRPC that need to operate on the database but are locked out due to the ongoing transaction.

This patch avoids that by creating a private event loop during transactions, so no unexpected operations fire.
