Grouper changes cause change log temp entries, these get processed, and then are pumped to change log consumers.  The first process is the change log temp processor

- 8% - deleting from temp change log

- 10% - querying member in point in time

- 10% - verifying membership doesn't already exist in point in time

- 1.5% - querying group in point in time

- 1.5% - querying field in point in time

- 7.3% - checking if membership is being re-enabled (was previously disabled)

- 15.4% - finding flattened memberships

- 14.8% - saving change log entries
