Given I have started Tails from DVD without network and logged in 1:14.047
And I prepare Tails for memory erasure tests 0.385
When I start a process allocating 128 MiB of memory with a known pattern 2.243
# Since Debian Trixie we only get 99.610% coverage (tails#21012)
Then patterns cover at least 127 MiB in the guest's memory 3.243 
Pattern coverage: 100.395% (127 MiB out of 127 MiB reference memory)
When I kill the allocating process 0.774
Then I find very few patterns in the guest's memory after 5 seconds 7.784 
Pattern coverage: 0.000% (0 MiB out of 1477 MiB reference memory)
