There's plenty of things that you're obviously supposed to worry about in unsafe code; such as making sure that you don't dereference pointers to invalid data, and that you don't use something after it is freed. But oftentimes there are problems that are not so obvious, and you might forget to think about them even if they are mentioned in the docs of an unsafe fn!

This book is a (modest) collection of those unsafe "gotchas."
