This reverts commit fb8f110e69.
realistic.files was meant to work just fine with short files. Commit
91c4f88860 has a fix for the verifying
side, to support short files.
Conflicts:
s3tests/realistic.py
Given a tuple of tuples, construct several files() generators, and
yield from those randomly. Randomness is weighted based on the number
of files remaining in each group.
The file verifier will now correctly verify small files (smaller than
the md5 digest size), as long as the data that is there matches what
the digest would be.
