I wasn't able to duplicate this with an underlying ext4 file system, with the
loop file system being ext2, using a 3.5 kernel on a system with 16G.
I tried both using a variety of small and medium sized files, as well as one
very large file, and I didn't see any unexplained stuttering in write
bandwidth. (There were times when cp -r was clearly writing to the in-memory
page cache, and the writeback hadn't begone yet. There were also times when
we couldn't do any more writing, because we were busy reading from the source
drive. But it all looked pretty normal to me.)
