Subject: [PATCH] git-svn: Fix termination issues for remote svn connections

When using git-svn in combination with serf-1.2.1 core dumps are
created on termination. This is caused by a bug in serf, a fix for
the bug exists (see
Nevertheless, I think it makes sense to fix the issue within the
git perl module, too. The change frees the private copy of
the remote access object on termination which prevents the error
from happening.

Note: Since subversion-1.8.0 and later do require serf-1.2.1 or later,
the core dumps typically do show up when upgrading to a recent version
of subversion.

Credits: Jonathan Lambrechts for proposing a fix to
Evgeny Kotkov and Ivan Zhakov for fixing the issue in serf and
pointing me to that fix.
Junio C Hamano for proposing a great code comment.
Kyle J. McKay for testing against latest serf (1.3.1).
... and various others - thanks!
