I have some patches applied which can be seen here: http://www.sodface.com/repo/index/aports/althttpd I applied the same patches to the static glibc build. > 4. Is the process multithreaded?

Furthermore, each process only lives for the duration of a single connection, which means that althttpd does not need to worry too much about memory leaks. These design factors help keep the althttpd source code simple, which facilitates security auditing and analysis.
