If generic/437 is run before generic/420, the latter fails with: 4c4 < stat.size = 2048 --- > stat.size = 2097152 because both use $TEST_DIR/testfile. generic/437 leaves it at 2M, while generic/420 assumes that it is empty (or at least smaller than 2048 bytes). Use a private test file (testfile.$seq) and truncate it on open just in case.
