Yes, it is expected and well-known that the client's memory usage is
potentially unbounded for commits; the more items sent in a commit,
the more memory the client will use, although the memory growth is by a
tiny constant factor.

The design of 'svn commit' and 'svn import' has the client holding a
list of committed objects in memory.

52000 files multiplied by a tiny constant? Yeah, that would still be a
measurable amount of memory during 'svn import'.

But are you really getting 100 megs of client memory when doing a
checkout of 52000 files? That surprises me somewhat.
