FWIW, testing with ltp, I noticed a new failure in logs. It turns out
to be intermittent, but the testcase mostly fails.
rtbox:~ # /usr/local/ltp/conformance/interfaces/sigtimedwait/sigtimedwait_1-1.run-test
Test FAILED: sigtimedwait() did not return in the required time
time_elapsed: 1.197057
...come on, you can do it...
rtbox:~ # /usr/local/ltp/conformance/interfaces/sigtimedwait/sigtimedwait_1-1.run-test
Test PASSED
#define ERRORMARGIN 0.1
...
if ((time_elapsed > SIGTIMEDWAITSEC + ERRORMARGIN)
|| (time_elapsed < SIGTIMEDWAITSEC - ERRORMARGIN)) {
printf("Test FAILED: sigtimedwait() did not return in "
"the required time\n");
printf("time_elapsed: %lf\n", time_elapsed);
return PTS_FAIL;
}
Looks hohum to me, but gripe did arrive with patch set, so you get a note.
