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
Before features/support/hooks.rb:265 0.002
Steps
Given I have started Tails from DVD without network and logged in 9.090
And I prepare Tails for memory erasure tests 0.506
When I start a process allocating 128 MiB of memory with a known pattern 1.320
Then patterns cover at least 128 MiB in the guest's memory 3.859 
Pattern coverage: 100.000% (128 MiB out of 128 MiB reference memory)
When I kill the allocating process 0.319
Then I find very few patterns in the guest's memory 4.323
9.961% 
9.961% of the free memory still has the pattern, but less than 0.800% was expected.
<false> is not true. (Test::Unit::AssertionFailedError)
