If so, we could mark these two bugs as the cause for resolution. (We could also do try builds including only one of the two patches to see which patch in particular solved the regression, for completeness) This is kinda tricky to confirm. There seems to be a fix for the build times. Still, the [plain](https://treeherder.mozilla.org/perf.html#/alerts?id=17471&filter=plain&page=1) builds haven't improved at all.
