"memfd" (memory file descriptor) lets us open pseudo-"files" that are not actually stored in the "real" file system. This feature is only available on Linux.

However, unlike a regular file, it lives in RAM and has a volatile backing storage. Once all references to the file are dropped, it is automatically released.

The recommended way to import this library is:

import qualified Memfd

There is one central function:
