<!-- Please describe your changes on the following line: --> Implements feature #19223 --- <!-- Thank you for contributing to Servo! Please replace each `[ ]` by `[X]` when the step is complete, and replace `__` with appropriate data: --> - [x] `./mach build -d` does not report any errors - [x] `./mach test-tidy` does not report any errors - [x] These changes fix #19223 (github issue number if applicable). <!-- Either: --> - [x] There are tests for these changes <!-- Also, please make sure that "Allow edits from maintainers" checkbox is checked, so that we can help you if you get stuck somewhere along the way.--> <!-- Pull requests that do not address these steps are welcome, but they will require additional verification as part of the review process. --> WIP. @jdm - this is the new profiler : "Blocked at IPC Receive" Should I dig through all the calls to `ipc::channel` and replace them with this profiled `IpcReceiver`?
