Review comment:
What will happen if `blobStore.setBlobMeta` succeeds then
`blobStore.updateLastModTime()` fails? Or nimbus crashed before
`blobStore.updateLastModTime()` can run?
Looks like supervisors will not be notified for this blob update. We should
update the timestamp before doing the actual operation.
