# Will test following scenarios:
# 1. Hit crash point while writing redo log.
# 2. Hit crash point on completion of redo log write.
# 3. Hit crash point while dropping indexes.
# 4. Hit crash point on completing drop of all indexes before creation of index
#    is commenced.
# 5. Hit crash point while creating indexes.
# 6. Hit crash point after data is updated to system-table and in-memory dict.
# 7. Hit crash point before/after log checkpoint is done.
