Oh - it's not like that.  It's transactional.

One time, gather a bunch of entropy, and write it to disk to create the initial file.  Subsequent times, read the file from disk, and change it.  It's a very fast file open / read / write operation, for the purpose of benefitting from the initial entropy gathering, but every time the file is read it must be changed.
