Dev server hangs on Windows 10

[csboling]

Windows 10.0.19043

$ deno --version
deno 1.21.0 (release, x86_64-pc-windows-msvc)
v8 10.0.139.17
typescript 4.6.2

Attempting to load http://localhost:8000 after running deno task dev, the console continually outputs

Download http://localhost:8000/app.js?ts=1651035243824
Download http://localhost:8000/app.js?ts=1651035244130
Download http://localhost:8000/app.js?ts=1651035244435
Download http://localhost:8000/app.js?ts=1651035244741

about 3 times per second, and the page never loads in Firefox or Chrome. Same behavior running curl http://localhost:8000.

With deno task start, the task completes and the page loads and renders "@_@" successfully.

As a control, the development build works fine for me on an older machine running Arch Linux.

Oh interesting, we haven't had a chance to do much testing on windows, but it sounds like an issue with our dev server. I'm going to move this ticket to the main Ultra repo. We have some updates to our dev server in the next release, we can try testing against it.
