- consult font text-property <-- potential race condition?
This code is all serial; it can't have race conditions. Why did you
think there was one? Perhaps that is a misunderstanding that is worth
identifying so we can clear it up now.
i know emacs separates the display into its own thread. the emacs display is
customizable w/ elisp that may eventually lead back to calling current-column.
not knowing the details for text-property access from C, i imagine some lock
that must be manipulated in precise order. this is because i haven't read
that part of emacs, foolishly trusting my instincts to cover for my ignorance.
in any case, when retooling caching schemes, there is always a possibility of
offloading the task to another thread. (sometimes i like to think of things
w/ parallel operation in mind, even if not needed immediately -- headed for
that emacs uproc, you know. ;-)
