-# Test summary:
-#
-# io-1.* -  Test that quick-balance does not journal pages unnecessarily.
-#
-# io-2.* -  Test the "atomic-write optimization".
-#
-# io-3.* -  Test the IO traffic enhancements triggered when the 
-#           IOCAP_SEQUENTIAL device capability flag is set (no 
-#           fsync() calls on the journal file).
-#
-# io-4.* -  Test the IO traffic enhancements triggered when the 
-#           IOCAP_SAFE_APPEND device capability flag is set (fewer 
-#           fsync() calls on the journal file, no need to set nRec
-#           field in the single journal header).
-#
-# io-5.* -  Test that the default page size is selected and used 
-#           correctly.
-#
-# io-6.* -  Test that the pager-cache is not being flushed unnecessarily 
-#           after a transaction that uses the special atomic-write path
-#           is committed.
