Below I'll attach the IRC transcript regarding today's repository wedgitude. If you don't know what I'm talking about, read this thread: http://www.contactor.se/~dast/svn/archive-2003-08/1704.shtml Summary of the IRC transcript: Revision 6764 exacerbated a problem with our BDB usage. We're making way too many transactions; we should stop making them for read-only operations, and use them as little as necessary for read/write operations too while we're at it. Revisions before 6764 are able to serve 3 simultaneous checkouts of the Subversion trunk from http://localhost/. Revision 6764 and after always lock up; this is reliably reproducible. See the above thread and the IRC transcript for details. Mike Pilato points out that this change is not easy :-), we'll have to think carefully.
