Hi Cyril,

It sounds pretty good and we would select a suitable oom_score value for library process(It seems that the child process will inherit the settings of the parent process).

And, in some stress test scenes, we might run LTP testcases with other testcases concurrently since the other testcases(for example: testcases in open_posix_testsuite) have no timeout limit or have no flexible timeout mechanism,

The stress test's main process would kill the testcase which is timeout.
