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.
