+Subject: [PATCH hare] Comment out assertions that fail on aarch64
+
+See #766
+
+I really would prefer not to do this, but these bugs are a bitch. I
+can't reproduce them on any of my aarch64 machines and it's totally
+non-obvious what might be causing them. Because they don't fail on every
+aarch64 machine I can get my hands on, I am reluctantly willing to
+disable them on the basis that they /probably/ work for most people.
