Revert didn't come clean. mek@, please look at this regression.

Revert "Fix behavior around closed message ports."

This reverts commit 419b66b54c98e04141e5e966d905dbb371314770.

Reason for revert: Depends on MessagePort onion-soupification, which
needs to be reverted for performance issues.

Original change's description:
> Fix behavior around closed message ports.
> 
> Connect a closed message port to a dangling message pipe to make sure
> messages posted to the port end up getting lost, even after the message
> port is transferred to a different process.

I've reverted the CL that depended on the problematic one, so hopefully that one should revert cleanly now. No idea yet what would cause this regression though. And as you say opening the after trace seems to cause chrome to get very unhappy...

Hmm, after ~10 minutes of waiting trying to open the after trace the tab crashes (presumably because it ran out of memory)...

Trying to run the (desktop version of) that long_running:tools:gmail-foreground benchmark locally fails with "OverflowError: size does not fit in an int" when trying to gzip the serialized trace data... Obviously something really wrong here, just not sure what.

#9: that just means the trace file is way too big. :-(

We have script to help deal with that:
1) https://cs.chromium.org/chromium/src/third_party/catapult/tracing/bin/html2trace?q=html2trace&dr=C&l=14 which will unpack the HTML trace file to multiple raw json file. Usually the one with biggest size is the Chrome trace 
2) Once you have the JSON form of the trace, https://cs.chromium.org/chromium/src/third_party/catapult/tracing/bin/slim_trace can be used to shrink the trace by discarding certain events.

Thanks. What seems to be the main difference is that the bad traces have tons upon tons of InputLatency related events. But that probably is just a symptom of whatever else is wrong. At least it's fairly trivial to reproduce this locally. (and fwiw the revert seems to have almost made it through the CQ)

Okay, I'm pretty sure I figured out the bug (and its fix https://chromium-review.googlesource.com/c/chromium/src/+/699159).
Should I land the fix directly, or still revert first and then reland with the fix included? (sorry, the previous revert attempt failed with merge conflicts after all trybots passed)

I recommend land the revert first, then land the revert + fix. That way we know the full impact of your CL after fix.

Works for me. Hopefully there won't be more merge conflicts with the revert.
