should there be a way to cancel/abort an import in progress?

Just after starting an import where the export contains ~10K posts and ~10K terms I realized that the export was not the one I wanted to import and wanted to cancel the import. But there is no way to do so.

So I just had to wait the MANY minutes for it to finish. It would be good to allow an in progress import to be canceled/aborted.

p.s. that import took 30 mins.
