Indeed, that’s a straightforward solution. Not sure if
the Emacs lock file mechanism is fast enough to run for
every write, though (Emacs doesn’t seem to expose
UNIX flock/fcntl stuff).
There’s also a question of should we try to make write from an Emacs
visible for read from another Emacs.
AFAIC it doesn’t make much sense if we just want to persistent
backing storage. Should we also consider the (ab)use
as an IPC channel?
Best,
Qiantan
