The "Import schema" dialog from the Wikibase extension has two issues:

• the Cancel button does not have a proper label
• importing the schema should close the dialog (currently one has to click the Cancel button afterwards, which is counter-intuitive since we do not want to cancel the import)

To Reproduce

Steps to reproduce the behavior:

1. First, open the dialog
2. See the improper l

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
