Hm. Running this test under CLOBBER_CACHE_ALWAYS I see that the VACUUM
FULL step takes 31 seconds (and the test succeeds). This is not
top-of-the-line hardware by a long shot (Intel(R) Core(TM) i7-4600U CPU
@ 2.10GHz) but I can believe that the other machines are slower or
busier.
Or there might be a completely different explanation ...
