I have some large projects that require launching where I really need the autosave period to be closer to 60 minutes. I use a few Windows shortcuts on my desktop for some common large OpenRefine projects that I sometimes cross with, etc. The problem is that I cannot easily use the Windows shortcuts to launch these particular large OpenRefine projects because I cannot also save the shortcuts with

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
