Details:
`dtable_for_class' contains some logic for waiting for an `initialize' call in
another thread. This seems to break when the other thread is similarly
waiting for us.
I have attached a test-case which reproduces this behavior on every run on my
computer using revision 28758 on GNU/Linux. I have also attached the Helgrind
log of a single run.
