No it's not. Multiple instances has absolutely nothing to do with what 
the shell returns when asked to run a program. In this case, it does

	result = execve(argv[0], argv, envp);
	/* execve() only returns on errors, so hint what went wrong */
	exit (-errno);

and since ENOENT == 2 this results in a return code of -127 on all 
architectures that implement the two-complement bit pattern.
