Periodically the program seems to crash with no warning or error message printed. It seems to happen only during processing of http requests, specifically at the end of the request.

I've tracd it down to happening when connections are closed too quickly. Steps that I used to reproduce the issue on my machine:

Open up the index page in a web browser
Hold down F5 in the browser until it crashes

From running it under strace it appears that it gets sent SIGPIPE during a write syscall.

After switching to using the send() syscall instead of write(), the crashes don't occur anymore. Still need to do some work to clean this fix up.
