+Subject: [PATCH] Fix flaky test_cache_last_used_update
+
+Sometimes time moves slowly and strict comparison is not enough:
+
+```
+>       assert now < node_cache_item.last_used < time.time()
+E       assert 1614147958.869299 < 1614147958.869299
+E        +  where 1614147958.869299 = <parso.cache._NodeCacheItem object at 0x10456fe80>.last_used
+E        +  and   1614147958.869299 = <built-in function time>()
+E        +    where <built-in function time> = time.time
+
+test/test_cache.py:149: AssertionError
+```
+
+In particular, macOS timings can be a bit coarse.
+
+The test failure is from Apple Silicon M1.
