Feature System memory erasure on shutdown
As a Tails user when I shutdown Tails I want the system memory to be free from sensitive data.
22.018
Scenario Erasure of memory freed by killed userspace processes
Before features/support/hooks.rb:269 0.003
Steps
Given I have started Tails from DVD without network and logged in 8.511
And I prepare Tails for memory erasure tests 0.496
When I start a process allocating 128 MiB of memory with a known pattern 2.372
Then patterns cover at least 128 MiB in the guest's memory 4.754

Pattern coverage: 100.000% (128 MiB out of 128 MiB reference memory)

When I kill the allocating process 0.289
Then I find very few patterns in the guest's memory 5.593
9.876% of the free memory still has the pattern, but less than 0.800% was expected.
<false> is not true. (Test::Unit::AssertionFailedError)
