[Bug 1065] New: T.sigconcept{37} cause T.sigconcept{41} to fail

Isolating T.sigconcept{41} by running a single test case works fine. However, if
we run the whole T.sigconept, T.sigconcept{41} will fail.  We have tried to
narrow down the failure and have found that the failure was due to T.sigconcept{37}.

The Test Suite expectation is that the SIGINT interrupts the pause() call. When
that one returns, calls alarm(0) and returns from interrupt() routine and ch_t41
in that case calls kill (getpid (), SIGKILL).

      ret = write(loop_fildes, (char *)&chr, 1);
      err = errno;
         if (ret == 1)
            (void) pause();

We believe that the uage of the pause in this case is not appropriate.  It needs
to block the signals it cares about and then use sigsuspend.
