(1) With the Linux kernel >=2.6.20, "make check" occasionally fails, due to
subsecond timestamps sometimes being truncated and sometimes being rounded

Rsync doesn't do any rounding, so I don't know where the inconsistency
would be. We just set the desination time based on the mtime value, and
the tls program outputs an interpretation of the mtime value.
Yesterday I did some tests (on jfs with subsecond timestamps, ext2 doesn't
have them):
True, rsync just truncates, i.e. ignores the fractional seconds, as do
freerdist-0.92 and (GNU) tar.
However, "cp -p" and "touch -r" round to the nearest second. So it seems the
failures are caused by comparing a directory created by "cp" with one
created by "rsync". Since spurious failures from "make check" defeat the
purpose of a test suite, it might be a good idea to avoid such comparisions.
