						is big enough to kick-off the background compaction. The test waits couple of seconds and then

						checks the database size and free space to verify that the background compaction really compacted

						the database.

						Iteration 2:

						background compaction will shrink the database size to be less than 4Gb.

						After iteration 2 the test performs an INSERT transaction and increases the database size to be
