Fuseki is properly managing transactions for the underlying datasets
update is a general purpose command that doesn't have awareness of transactions
(though it probably could/should)
Use tdb2.tdbupdate to run updates on TDB2, note that in the command line tools
there are a variety of tools named tdb2.<tool> which should be used for
interacting with TDB 2 databases in preference to the general purpose commands.

What/Who is causing this problem? Am I using the wrong command-line tool?
And is there a way that I can fix this?
Note: if I use Fuseki everything seems to work fine. That is, if I use the
same dataset definition in the fuseki assembler file, and if I issue the same
update query from the fuseki web UI. But if I use the "update" command line
tool instead, I get a transaction error. I'm not sure what fuseki is doing
differently...
