I've looked into the patch set and have some more questions:
1. What if we flush many times? Is it supposed to overwrite injection_points.data?
2. What if we restart many times? first startup will remove the file... maybe remove it explicitly?
3. InjectionPoint private data is not handled, is it OK?
4. How session-local points are expected to be flushed? into which session they will be loaded? Maybe let's document that they are not saved?
Besides these, cool new abilities and a test for a bug, looks good to me.
Best regards, Andrey Borodin.
