 something faster than difflib, which is after all pure Python.
 Another approach is to just store the gzipped full text of big files,
 though perhaps that's too perverse?
+
+The iter method here will generally read through the whole index file
+in one go.  With readahead in the kernel and python/libc (typically
+128kB) this means that there should be no seeks and often only one
+read() call to get everything into memory.
