It's not like we have to parse the entire file everytime we append a
message, in fact - all we have to do is lseek() to the end of the file.
In the case of fetching a message, again, we lseek() to the point in the
file we want. We have all the offsets cached.
Btw, an lseek() isn't really all that slow.
