When I try and clone a repository like so 'darcs get foo foo-cloned' with my
current largish and unfortunately non-OSS-licensed repository, I get an 'out of
memory' error.

Strangely enough, 'darcs get http://my-darcs-repo-machine/foo' foo-cloned works
just fine.  Somehow, 'darcs get' over HTTP does not exhibit the issue, but
'darcs get' on the local file system does.

This happens on 2.0.0pre3 and current unstable head.  I am not sure if it
happens on earlier versions - I will check.  Watch this space...
