With svn+ssh:// and a 100MB random-bytes file I can reproduce the
memory usage. The only problem is ... it doesn't seem to be a problem
in my functions, but in subversion:

The memory gets allocated to increase a stringbuf ... although revert.c:176 says
stream=svn_stream_from_aprfile(a_stream, subpool);
so it should go directly into a file.
(BTW, the same happens on update - and I can reproduce it there, too.)
I've got libsvn1=1.4.4dfsg1-1.
So, for a summary -- I can see the problem, but as yet I don't
know where it happens.

Phil
