BTW, is there a facility already present in ECL so that I can in the<br>
top-level decide which unix signal to ignore (a-la sigaction(2)<br>
SIG_IGN), and block/unblock it on a per-thread basis (i.e. a-la<br>
pthread_sigmask(3))? Or must my code use inline C as necessary to do<br>
this? I guess that such code would have no relevance on non-POSIX OSs<br>
