This doesn't in itself make them thread-safe, but it provides a basis to do so by avoiding dependence on the Preferences service at textrun-construction time. The FontPrefs record is inert once constructed, so one approach to worker-thread use would be to make it refcounted, and have the worker hold a strong reference to the record it's using, so that it won't be affected if the main thread handles a pref-change and replaces its FontPrefs. Alternatively, maybe we can just protect access with the same lock as other uses of the font list, once that is in place (bug 1756474).
