I don't think so.  git-svn is going right into the SVN repository.
THere's no delayed update or anything like that that's affecting this
action.

What's happened is someone has made an upstream commit into the SVN repo
between the time you last updated your local tree via git svn rebase and
hte time you tried to push via git svn dcommit.

Moving to GIT exclusively won't really change this because the same
situation happens if you git pull, change locally, then git push.  If
someone changes the remote repo between the pull/push you get a conflict.
