Description

In the step "I find very few patterns in the guest's memory" in memory_erasure.feature we set max_coverage = 0.0025, i.e. we allow less than 0.25% of memory to not be wiped. The efficiency of our memory erasure approach seem to differ depending on kernel version, architecture (64-bit vs 32-bit) and the phase of the moon, so we sometimes have to arbitrarily bump it as well.

We should come up with a sound value for max_coverage, preferably based on Hard Science™.
