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.
