Yes, Subversion will only allow one commit to be taking place at a
given time, so there can only be one post-commit hook running at a
time. However, if you spawn off a process in your post-commit hook,
then the post-commit hook will exit before your script is done, so
there could be multiple copies of your spawned script running at a time.
