VCF store with ~2000 gVCF files, can't export

Before turning the keys over to our researchers, who I know are know are going to try to export data to multi-sample gVCF, I thought I’d try something simple. So I imported a subset of our gVCF data into a bucket on S3. If I run tiledbvcf list on that bucket I eventually, like 5 minutes, get a list of sample names back.
