> Clear the signal mask of the child when launching with posix_spawn.
> 
> SIGQUIT signals are handled on non-Java Threads by the VM.
> For Java threads the signal mask blocks SIGQUIT.  
> The ProcessBuilder uses posix_spawn on all platforms to create new processes.
> Without a specific request, the child process inherits the signal masks from the parent.
