---------------------------------------------

@Till, any thoughts on who could best do this?  (Abdullah? Ian?)
Who's our loader expert nowadays...?
I'm sure it's simple...

> We have a really sucky response to an accidental "overload" - i.e., if you try to load
something 2x:
>  "Internal error. Please check instance logs for further details. [NullPointerException]"
> Here's a simple reproducer based on our 101 scenario (an open version thereof, actually):
> drop dataverse OpenTinySocial if exists;
> create dataverse OpenTinySocial;
> use dataverse OpenTinySocial;
> create type FacebookMessageType as {
>         message-id: int64
> };
> create dataset FacebookMessages(FacebookMessageType)
> primary key message-id;
> load dataset FacebookMessages using localfs
>     (("path"="127.0.0.1:///Users/mikejcarey/tinysocialdata/fbm.adm"),("format"="adm"));
> load dataset FacebookMessages using localfs
>     (("path"="127.0.0.1:///Users/mikejcarey/tinysocialdata/fbm.adm"),("format"="adm"));
