Is there any reliable way to get (or conservatively estimate)
the size of a buffer when written to file?
I’m thinking about using it for an optimization for persistent kv store.
If we know a log entry, when written out, is shorter than PIPE_BUF,
then we can skip the file locking/unlocking.
Emacs lock file doesn’t seem to be particularly fast.
Best,
