[Daniel van Vugt]

Tests fail with: std::exception::what: Failed to read from device: /dev/random after: 30 seconds

Test case:
  1. Reboot your system
  2. mir_acceptance_tests --gtest_filter="PromptSessionClientAPI.*"

Expected: Tests either pass or fail quickly (see bug 1540731)
Observed: Tests hang for a long time and eventually report:

ERROR: /build/mir-UeyFew/mir-0.19.0+16.04.20160128/src/cookie/authority.cpp(112): Throw in function mir::cookie::Secret get_random_data(unsigned int)
Dynamic exception type: boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<std::runtime_error> >
std::exception::what: Failed to read from device: /dev/random after: 30 seconds

unknown file: Failure
C++ exception with description "Failed to start server thread" thrown in SetUp().

Workaround:
Log in to your system, move the mouse around and use it for a while before running tests.
