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.
