Implement the ability for the test_io mechanism to abort after n reads
	or writes to a particular block.  The block is specified by
	TEST_IO_BLOCK environment variable, and the read/write count
	by the TEST_IO_READ_ABORT and TEST_IO_WRITE_ABORT environment
	variables.  The block data is now only dumped if the 0x10 bit
	is set in TEST_IO_FLAGS.
