Description

bail if system() or popen()ed programs were killed:

As mentioned, system() ignores SIGINT and SIGQUIT. This may make programs that call it from a loop uninterruptible, unless they take care themselves to check the exit status of the child. E.g.

while (something) {
int ret = system("foo");
if (WIFSIGNALED &&
(WTERMSIG SIGINT || WTERMSIG(ret) SIGQUIT))
break;
}

I went through all the system() and popen() calls and made sure we were checking the return code for
WIFSIGNALED, and if we were, I throw an exception. Rerunning tests now..
