I recently installed the new version of Ubuntu (24.10) from 
scratch. Opening VSCode with code-d makes it unusable, and even 
without plugins, simply running dub from VSCode's terminal 
consumes 100% of the CPU and 8GB of RAM.

The reason for this is that VSCode raises the open file ulimit 
significantly. As a result, when Phobos performs a fork to start 
a process, it triggers a known bug [1].

While waiting for the PR to be merged, you can launch VSCode by 
setting a lower ulimit, for example with:

```bash

ulimit -n 16384
/opt/your_vscode_bin_path "$ "
```

I hope that once the pull request is merged and the new compiler 
(2.110) is released, the tools will be compiled with version 
2.110 instead of 2.109; otherwise, the bug will persist until the 
next release.

As I’ve mentioned before, I firmly believe that everything 
released should go through a bootstrap, including the compiler 
itself (i.e., once 2.110 is compiled with 2.109, 2.110 should be 
recompiled with itself to take advantage of any fixes applied).

Meanwhile another patch has been merged, I'm not clear if it 
resolves the problem on Ubuntu or not, I hope so. In that case it 
should work on 2.110, right?

No, that one was also to master, so it will be in 2.111 unless 
someone cherry-pick's it to stable.

All we can do is hope that it's a problem with my configuration 
then, or the issue will soon explode.
