Noca is a shared library that prevents the page cache from filling with data that we know we only need once. It hooks read, lseek, and close. If some conditions are met, they trigger an fadvise call so that the memory is freed. An example of its use could be to limit the page cache of a "tar zxvf" operation to a specified size, no matter how big the archive is.
