 // This class sets up the environment for running the native tests inside an
 // android application. It outputs (to a fifo) markers identifying the
 // START/PASSED/CRASH of the test suite, FAILURE/SUCCESS of individual tests,
 // etc.
 // These markers are read by the test runner script to generate test results.
 // It installs signal handlers to detect crashes.
