Sounds like the right fix is to revert last month's addition and instead
add a new test, which can use an explicit buffer size to be a robust test
of what it intends to test regardless of the details of the environment.
Or you could just wait until someone makes a version of tmpfs that uses
megabytes or more for st_blksize and it breaks again.
