Because the whole point of the XInternAtoms function is to not block on
any of the replies until all of the requests have been made. The
fallback code, when memory allocation fails, is very slow: it waits for
N round-trips to the server, if N atoms are requested. The other code
waits for 1 round-trip, no matter how many atoms are requested.
