I hacked on httpdito some more, and it has been improved in several ways:

- it now forks so that it can handle multiple concurrent connections (up to a limit of 2048);

- it no longer uses libc at all, so it's down to 2088 bytes (I had it lower, but then I added forking);

- it's less complex now that it only has one way of invoking system calls instead of two;

- there are some performance results in the comments.

- it has a name, "httpdito";

- strlen works correctly.

Probably nobody will read this comment here, but I thought it was worth mentioning.

Down to 1928 bytes now, and has timeouts for robustness. You can still DoS it but it takes more work.
