I forgot that I had kept a very recent copy of the repository
(obtained with dump + load) on a Debian/unstable machine (the goal
was to do some tests before the server upgrade). So, I could test
with it, still using svn+ssh (but here, localhost). An "svn blame"
on the same file takes a small memory footprint for both the svn
client and svnserve (around 16 - 30 MB for resident memory, around
250 MB for virtual memory).

So, I suppose that the memory problem was a bug in 1.8.8.
