looks like a couple of other gtests use the tmp dir too


grep -nH -r get_temp_directory  *
logging/logTestFixture.cpp:40:                         os::get_temp_directory(), os::file_separator(), os::current_process_id(),
logging/logTestUtils.inline.hpp:93:static const char* tmp_dir = os::get_temp_directory();
logging/test_logFileOutput.cpp:173:  ss.print("%s%s%s%d", os::get_temp_directory(), os::file_separator(), "tmplogdir", os::current_process_id());
os/linux/test_cgroupSubsystem_linux.cpp:45:  path.print_raw(os::get_temp_directory());


but seems the others at least clean up the created files as far as I can see.
