Just for record: I've solved my problem. The bug is really server-side. SVN client does not issue any additional http requests, and does not re-use GSSAPI token. It is server who re-validates the GSSAPI token million times. You can find all the details in subversion/mod_dav_svn/authz.c:allow_read() function.
In SVN 1.5, there is "SVNPathAuthz short_circuit" directive, which fixes the problem (at least for me). The directive is dangerous -- see http://archives.devshed.com/forums/development-94/svnauthorizationshortcircuit-or-something-similar-2278264.html for some details. So, this bug looks like a "design feature". However, from user point of view, it is very strange to get incomplete checkout with "success" status. With best regards, Alexandra. -- Alexandra N.
