----------------
Perhaps a "simpler" fix would be not to use the main thread here, i.e. should use `TG.spawn`? However, that assumes that `getThreadIndex()` is only for use in the "`parallelFor`" style functions otherwise the other parallel functions would also need to avoid using the main thread too.

I'm surprised that this hasn't been causing more issues.
