Review request for Plasma.
Changes
-------
Now that I think about it again, the race condition doesn't really matter here.
It won't be the only place where the shared config would be accessed from
different threads.
Just from a quick look:
IconItem - queries theme in updatePolish = main thread
SvgItem - queries theme in updatePaintNode = render thread
So I think we should fix the other items with this in mind = don't access
Plasma::Theme from render thread.

Repository: plasma-framework
Description
-------
svgElementsCache may be created on render thread and deleted on main thread,
which will make KSharedConfig crash (it uses per-thread storage).
Diffs (updated)
-----
src/plasma/private/theme_p.cpp 2faced8
Diff: https://git.reviewboard.kde.org/r/127112/diff/
Testing
-------
I couldn't reproduce the crash, even with QSG_RENDER_LOOP=threaded (on Intel
GPU).
I think we can't just call reparseConfiguration in discardCache, because there
will be race condititon (reparseConfiguration running on main thread and config
being accessed from render thread).
Thanks,
David Rosca
