That's only my speculation. I feel that we may occasionally fail to execute the following configuration.  Maybe it returns false when the memory budget is tight. this patch reduce the memory requirement for stdout/stderr.


set_log_config("stdout", "logging=debug")
set_log_config("stderr", "logging=debug")


In the logs provided by David Holmes, we actually can see "header". 
It means that stdout/stderr streams are fine. gtest successfully captures and writes the contents to file. We didn't check the return value of set_log_config. I want to proceed to test only when set_log_config() is true.
