Remember the corollary of having safe arrays is that people can DoS
your server by opening a socket and writing .. and writing .. and
writing.  It's always a good idea to either implement your own
sensible maximums on the length of strings / arrays, or at least run
your module with a BSD resource-style limit (setrlimit(2)).
