Blocker Description
'svnadmin hotcopy' calls svn_fs_hotcopy_berkeley(), which ultimately ends up calling apr_file_copy() on each table-file. apr_file_copy() just reads BUFSIZ bytes at a time into a buffer and writes them back out again. According to BDB's docs, this might be problematic, we need to do more research on this. Here's some theoretical background from sleepycat: http://www.sleepycat.com/docs/ref/transapp/reclimit.html
