        Description

        Initially, the bug was discussed here:
        https://stackoverflow.com/questions/35264582/why-is-multithreading-slowing-down/35264813

        The method LCMSTransform.doTransform() is synchronized which means we cannot transform different images in parallel. See the link above for an example and additional details.
