 Per
 http://pubs.opengroup.org/onlinepubs/009695399/functions/sigaction.html,
 the sa_flags field can have the following values which imply behavior in
 the POSIX implementation:

 * SA_NOCLDSTOP - requires processes, unsupportable
 * SA_ONSTACK - requires unsupported sigaltstack, currently unsupportable
 * SA_RESTART - should be supportable
 * SA_SIGINFO - should be supportable
 * SA_NOCLDWAIT - requires processes, unsupportable
 * SA_NODEFER - should be supportable

 The purpose of this ticket is to review that the supportable sa_flags
 behaviors are supported or to implement the missing capabilities.
