When a user first logs into Wikidata, or logs out through the Manage Wikidata account option of the Wikidata extension and then logs in, the UX leaves the user wondering what happened since the login dialog disappears, leaving the user to assume they logged in successfully.

Proposed solution

Ideally, the current "logged in" dialog (bind="explainLogin") could actually be shown immedia

steps to reproduce

Write a loop, from 1 to 80000, each time add a random int to the max heap.

In theory it takes very little time(NlogN, N=80000, <1sec ), but the program does take a long time.

I'v also tested the BinaryHeap in https://github.com/SolutionsDesign/Algorithmia, it performs well, so it is probably due to the bad algorithm.

In the following file we have already ported some tests from Go to Rust:
https://github.com/crossbeam-rs/crossbeam-channel/blob/master/tests/golang.rs

The idea is to blindly port all the tests for Go channels line by line, which will give us additional confidence in the correctness of crossbeam-channel.

In the test file, you can find stubs with links to the original tests written in Go and
