This is why the add method is unsafe: "This method is unsafe because
it requires that the Handle is not moved while it is added to the

Ah, yes I failed to see the warning in the documentation. add()ing the
handle after moving it into the hashmap does seem to make things better.
Thanks for your help!

Hello all,
I have two somewhat related questions to ask you fine folks. I'm trying to
implement something that selects on a variable number of receivers, which
can change during program execution. I've been attempting to do so by
making Handles to those receivers and storing the handles in a HashM
