I have checked this, but that is not the problem.

What I did notice is something else. Part of a smaller tree I am 
syncing also has moved o being from a svn repository. Suddenly this one 
also slows down enormously.

Looking on the system I see 2 rsync processes. It also happens when 
rsyncing 1 file:

And it hangs. PS shows:

   501  3847  3831   0  31  0    97800   5004 -      S+    p0    0:00.14 
/usr/local/bin/rsync --rsync-path=/usr/local/bin/rsync --eahfs -e ssh 
-avu --progress gerben at mail.rna.nl:Library/Safari/Bookmarks.plist 
/Users/gerben/Library/Safari/Bookmarks.plist
   501  3860  3847   0  31  0    97864   1984 -      R+    p0    1:46.07 
/usr/local/bin/rsync --rsync-path=/usr/local/bin/rsync --eahfs -e ssh 
-avu --progress gerben at mail.rna.nl:Library/Safari/Bookmarks.plist 
/Users/gerben/Library/Safari/Bookmarks.plist

97864 is taking up 100% CPU almost.
