AFAICS, the threaded export is interesting mostly because of the cost
of running external programs. Could we do the latex export in the main
thread and then just do our converter stuff in a multithreaded way?
How difficult is that?
That's a good idea, but I have no idea how difficult it would be. I'm
also not sure how well this would work with our other export formats,
e.g., docbook and html. In those cases, we call external converters, as
well.
And if exporting to LaTeX is too slow, we just have to profile it and
speed it up.
It is a bit strange to me that libstdc++ can have this bug without a
solution in view. LyX is probably not the only GUI program that uses
threads with g++, is it?
One would suppose not.
