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.
