under some circumstances, libjemalloc2 hangs on arm64 architecture.
[test case]
the mariadb-10.1 autopkgtests, specifically when apt installing mariadb-server-10.1, will hang. It's possible the apt install mariadb-server-10.1 hangs outside the autopkgtests as well, but the test regression is very reproducable, e.g.:

note the failures for version 1:10.1. 38-0ubuntu0. 18.10.1
[regression potential]
this patch is already included in disco and later; regression potential should be low. Regressions would likely result in more/different hangs.
