OK, I added this little snippet:

	if (getenv("RDMAV_FORK_SAFE") || getenv("IBV_FORK_SAFE"))
		if (ibv_fork_init())
			fprintf(stderr, PFX "Warning: fork()-safety requested "
				"but init failed\n");

so that setting either RDMAV_FORK_SAFE or IBV_FORK_SAFE environment
variables forces the library to try to be fork()-safe.
