Block on LaunchProcess failing on specific bot

Block in a loop if we get a specific failure on a particular bot.
See environment variables at http://build.chromium.org/p/chromium.win/builders/Win8%20Aura/builds/20713/steps/views_unittests/logs/stdio for reference.

Timeout raise attempted at https://codereview.chromium.org/410353004/ so
that there will be time to attach a debugger.
