ancestor: use absolute_import

A few months ago, import-checker.py was taught to enforce a more
well-defined import style for files with absolute_import. However,
we stopped short of actually converting source files to use
absolute_import because of problems with certain files.

Investigation revealed the following problems with switching to
absolute_import universally:

1) import cycles result in import failure on Python 2.6
2) undetermined way to import C/pure modules

While these problems need to be solved, they can be put off.
This patch starts a series of converting files to absolute_import
that won't exhibit any of the aforementioned problems.

    f.write("\n")
finally:
    f.close()

now = os.stat(fname).st_mtime
while now == before:
    t = now + inc
    inc += 1
    os.utime(fname, (t, t))
