If process terminated before storage_lookup_patches, then no buildids can be found and function must return -1.

please write a better log message. Like 'spawning child to patch pid %d'.

This returns value. Check it.

Error messages are written inside stress_test_log_init.
Contrary to base process, children should continue work even if can't initialize log file.
Is it better for them to exit in case of logging error too?

Is it possible to just use strncpy and then check if last byte is zero? (this requires test_log_base to be declared static).

Sometimes during stress tests buildids can't be retrieved because process already terminated.
In this case "No patch(es) applicable to PID '%d' have been found\n" was printed, which is considered error by test scripts.
