seems like we want to check the sandbox on the connection resets. we may exception out of python too quickly before h2o can dump a gc/out of memory error to it's stdout. Special case the exception on the do_json_request, (try/catch) and wait a second and check the sandbox for errors. print a red message before we do that. That branch isn't taking if ignoreConnectionError, which is used when polling h2o during bringup, when connection exceptions are expected (they used to be ignored at a higher level ..i.e. at stabilize_cloud() etc.
Merge branch 'master' of github.com:0xdata/h2o
