It seems we can compensate this effect by changing the collector settings.
For instance, with collectgarbage("setpause", 150) I got the following
results:
20.9375
68.3876953125
79.7001953125
59.1376953125
70.4501953125
81.7626953125
45.2001953125
72.5126953125
83.8251953125
47.2939453125
74.6064453125
79.4814453125
56.0439453125
76.7001953125
69.0751953125
51.4814453125
78.7939453125
(On Linux, but compiled with -malign-double.)
Maybe the default should be changed.
