The volume was low on that recording. I hope you could hear it well.

A few comments on the part about when messages are copied
between process heaps:
- The general rule is that message passing is always
_conceptually_ copying. If/when the data is actually copied
may vary. For example, large binaries are not copied when
passed in a message, but are copied if changed. Small binaries
are kept on the heap and copied when passed in messages.
- The shared heap implementation didn't do anything special
at compile-time, but really did have one global heap shared by
all processes. The idea was to have a incremental garbage
collector, but this work was never finished.
- The (also experimental) hybrid heap implementation also has
a shared heap, but the shared heap is only used for data that
is passed in messages, and it's garbage-collected like all other
process heaps. Initially, data is copied to the shared heap the
first time it's sent in a message; if it is included in another
message, it needn't be copied again. The compiler could
potentially figure out if data is to be sent in a message, and
could then instruct the VM to create it on the shared heap.
This hasn't been implemented yet.
