In PyPiHostedFacetImpl on getIndex() createIndexAsset() is called which creates a TempBlob that is never cleaned up.
I believe the TempBlob created should be wrapped in a try block like the others so this TempBlob is deleted after getIndex
private Asset createIndexAsset(final String name,
final StorageTx tx,
final String indexPath,
final Bucket bucket) throws IOException
try (TempBlob tempBlob = storageFacet.createTempBlob(new ByteArrayInputStream(html.getBytes(UTF_8)), HASH_ALGORITHMS);
