Thanks for bringing the issue here to the list. First a couple questions to get our context right: what version of svn on the client and on the server? Is there a slow network between client and server, or are they on the same LAN? Just as background: svn:externals definitions can also optionally take a peg revision (the @REV notation) [1], [2]. Maybe in the future you can use the peg revision syntax to avoid this problem of the "external source" disappearing at some point in history.
