Jürgen -
this is due to the "dependencies" member on UOWTask becoming a Set as
of last night, and its handy that it raised that. changeset 1519
contains a bigger change that should insure that the "dependencies"
member should not be modified mid-stream...see if that fixes your
problem.

In my application I had a problem with self referencial mappers.
Currently I can not reproduce it in a simple example but the attached
diff solved the problem.
I got an error because task.dependencies was changed inside the
while loop.
I also tested the change against the tests in sqlalchemy.test.
Apart from the existing errors when running the test there was no new
error introduced.
