In tracking down a bug I found that in certain cases the database (H2?)
that comes with Wildfly will perform table-level locks. It definitely
does a table lock in transactions that require inserts. Not sure if it
happens on regular row updates.
Makes me feel like we have been really lucky altogether that we haven't
run into problems so far.
