Because LC can't do two things at once.

I've been using many of the parallel features in .NET recently. I've been
pretty impressed with how easy it is to get the hang of.

Node.js at its core uses an event loop to provide async (not quite real
parallel processing, however). Doing complex things with it was quite a
callback-nightmare until recently as things have started to mature some as
a result.

Not saying, to switch to those things but I could see the nodejs event loop
providing some inspiration to augment the concurrency features already
present in livecode.
