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.

Scenario Erasure of memory freed by killed userspace processes

Steps
Given I have started Tails from DVD without network and logged in 8.764
And I prepare Tails for memory erasure tests 2.992
When I start a process allocating 128 MiB of memory with a known pattern 4.183
Then patterns cover at least 128 MiB in the guest's memory 5.257
99.610% of the expected size (128 MiB) has the pattern, but more than 100.000% was expected.
<false> is not true. (Test::Unit::AssertionFailedError)
./features/step_definitions/erase_memory.rb:186:in `/^patterns cover at least (\d+) MiB in the guest's memory$/'
features/erase_memory.feature:17:in `Then patterns cover at least 128 MiB in the guest's memory'
Output 1

Pattern coverage: 99.610% (127 MiB out of 128 MiB reference memory)

When I kill the allocating process 0.000
Then I find very few patterns in the guest's memory after 5 seconds 0.000
