For performance or workaround reasons we sometimes have to avoid doing two conflicting operations at the same time, but we can still run any number of non-conflicting operations in parallel. MultiLocker (suggestions for a better class name welcome) blocks the calling thread until there are no threads attempting to run a conflicting operation.
