 Is using SIGEV_SIGNAL with AIO to deliver a SIGIO on
 completion fall under the heading of real time
 signals?
 If that is the case, SA_SIGINFO is not useful, because
 
 it gives you the same information in the (siginfo_t 
 *info) as the (int code) would contain. It is at least
 
 a bug in the documentation. In the man page it should 
 say that the siginfo_t does not get filled out, and 
 that SA_SIGINFO is just there for some level of posix 
 compatibility.
 
 If you're certain of this, this can be reclassified
 as an RFE, and I'll submit a docs bug.
