SIGCHLD *is* ignored by default (man 7 signal). In fact, system() itself 
blocks SIGCHLD (man system)!! Proprely written code uses wait() anyway 
regardless of SIGCHLD.

Completely disagree. Properly multithreaded programs block all signals 
in every single threads, except in specific threads that might NEED to 
receive them; and in particular, they do not allow one thread to signal 
a random other one.
