OS: Windows 10 Version 10.0.19045.2728

From deno 1.32.1+7722014 and up, running deno repl or just deno from certain directories causes the deno process to hang with no repl prompt and with excessive memory usage.

The bug is reproducible if running deno from C:\, C:\Windows, C:\Users, C:\Users\<current_user>, C:\Windows\System32, C:\Windows\SysWow64. At the same time runinng deno repl from C:\Users\<current_user>\Desktop or C:\Windows\System32\wbem proceeds as normal. These are the directories that I've tested which reproduced the bug 100% of the times. Other directories and drives seems unaffected.

The last unaffected canary version with available binaries to download is deno 1.32.1+e888c3f

Edit:
Just checked with the 1.32.2 release. It's still affected.

Edit2:
Checked 1.32.2 Linux under Windows WSL, it hangs when executing with the root dir (/) as the current directory.

Note that this occurs not only on Windows or WSL, but on Linux as well. #18540.

fix(repl): disable language server document preloading in the repl (#…

…18543)

This was an oversight because the repl uses the language server under
the hood. Also, never preloads from a root directory.

fix(lsp): add a document preload file system entry limit (#18553)

I was testing this out and it's badly needed. For now, it's not
configurable and limited to 1,000 file system entries.
