Comment(by dleuschner):
Does anybody have an idea what could be causing this behavior? Could it
have something to do with networking? Or FFI? Or any specific type-
system/language feature? Is there anything we should pay attention to?
Could the numbers after "isRetainer()" tell us anything? Although we
cannot open source our application code at the moment, we of course could
send it to you, Simon, so that you could, in principle, reproduce the
problem. But unfortunately it's still an awful lot of code and libraries.
I would try to write a simple test case but I have no idea what I should
include?
