Martin, I'm sure there are several developers who would be interested
in seeing this behavior first-hand. Is your repository private? That
is, could you make a tarball of it and provide a URL? (If the
contents are private, and you trust me not to disseminate them, you
could send me the URL privately).

Secondly (which should perhaps be "firstly") -- are you able to debug
this at all? I'm not sure where to start -- maybe running svnlook
under strace or something. Or, can you play with the number of files
in that directory and see how the behavior is affected? If you cut
the number from 4000 to 2000, is the time between each file is handled
also cut roughly in half?
