Hi devs,
while giving TSVN 1.6. some final touches, I ran into this one:
I just wanted to 'undo' (reverse-merge) a small, fairly recent
revision but it would TSVN over 10 minutes to complete.
Because this is a major performance issue IMHO, I tried to
reproduce it on my LINUX box - sadly with success. This is
what I found:

This is already quite bad but it gets much worse:
$ cd ~/Documents/subversion-1.6.0-rc3/subversion/svn
$ ./svn --version

Hopefully, someone can fix that or at least qualify the
issue in 1.6.0.
