--- Comment #4 from youenn fablet <youennf at gmail.com> ---
Testing the MessageChannel repro page, page consumes up to 8GB of memory, then GC kicks in and it continues over and over. This seems fine, not sure whether we could try to optimise things here.

Similarly, the web workers page is not crashing, although it eats up to 30GB of memory until GC happens and memory is down to a few MBs and does not increase anymore.
Not exactly sure why this behaviour happens, there might be things we could improve.
This does not seem critical though.
