I'd like to use this issue as a tracking issue for filling out gaps in wasmtime's introductory documentation. This includes our book (rendered), API documentation (rendered), and [examples](https://github.com/bytecodeallianc

What happened

Visual artifacts on crosshair

Game version

The auto-evo run start should be delayed until auto save has happened (or if auto-save is not on, until the fade is complete).

Should check if problem_dirs is a string before https://github.com/DMOJ/judge-server/blob/master/dmoj/judgeenv.py#L173, otherwise we will be watching nonsense paths,

nanovms/ops#525

We don't currently have an explicit test for futexes. We could use an exhaustive test that stresses both the futex interface as well as correctness on single and multiple-core instances. The test should run under both a Linux host and nanos as a parity check.

I following the guide from here https://github.com/nestybox/sysbox/blob/master/docs/developers-guide/build.md, download the source code from the release page but it's failed when try to run make sysbox like this:

OS version: Ubuntu 18.04.5 LTS
Kernel version: 5.4.0-48-generic #52~18.04.1-Ubuntu SMP

** Building sysbox **

docker run --privileged --rm --hostname sysbox-bu

We want to support long presses, not just double taps.

It will be great to see a tumbler at the web interface to turn on and off the internet connection for the scan.

I suppose, you can turn on/off it in drakrun/main.py file using ifconfig vif manipulation, like sudo ifconfig vifX.0 down at the "process" function. Plus self.current_task.payload.get to obtain the tumbler state.
