Seems like this hasn't fixed the problem: skink still fails on
this test occasionally.

https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=skink&dt=2021-10-22%2013%3A52%3A00
https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=skink&dt=2021-11-02%2000%3A28%3A30

Both of these look like

#   Failed test '000000010000000000000002 differs from 000000010000000000000002'
#   at t/026_overwrite_contrecord.pl line 61.
# Looks like you failed 1 test of 3.
t/026_overwrite_contrecord.pl ........
Dubious, test returned 1 (wstat 256, 0x100)
Failed 1/3 subtests

which looks like the same thing we were seeing before.
010e52337 seems to have just decreased the probability of failure.
