+MD4 file_sum
+
+  If we're doing a local transfer, or using -W, then perhaps don't
+  send the file checksum.  If we're doing a local transfer, then
+  calculating MD4 checksums uses 90% of CPU and is unlikely to be
+  useful.
+
+  Indeed for transfers over zlib or ssh we can also rely on the
+  transport to have quite strong protection against corruption.
+
+  Perhaps we should have an option to disable this, analogous to
+  --whole-file, although it would default to disabled.  The file
+  checksum takes up a definite space in the protocol -- we can either
+  set it to 0, or perhaps just leave it out.
