I think I am being bitten by concurrency issues when using 0.1.0. Are  
they supposedly fixed in trunk? In case they are, I could produce a  
suite of tests that fail against 0.1.0 and run them against trunk to  
see if they succeed.

What I am asking is whether there are any tests already for this, so  
I can see if my cases are already covered by those. If this is not  
the case, I might add my tests to the current suite.

Yes, the concurrency issues should be fixed in the trunk but no, there
are no tests yet to make sure.  Not all of the code is threadsafe tho.
None of the model.* classes should be considered threadsafe.  You'll
definitely need to provide your own synchronization if you want to do
something silly like, allowing multiple threads to modify a single Entry
:-).

A suite of concurrency tests would be very welcome.
