I am deliberately closing this as wontfix for the following reason: We don't
know whether this can be made threadsafe. But from the nature of this plugin
when multiple modules try to module one clone/working copy this will logically
(likely) not work. If someone can prove the opposite I'd be happy to reopen
this.
