PlotlyJS breaks when Julia is started with multiple threads

[Murari Soundararajan]

I am not able to produce any plots at all when running julia multi-threaded. I have attached the stacktrace as a separate file (plotlyjs_threaded.log), but as an example, something simple like the following:

using PlotlyJS
plot([1:10],[1:10])

which works when I start Julia single-threaded, fails with a ConcurrencyViolationError("lock must be held") when I start with multiple threads.
