"Busy" locals window screenshot

I first experienced this around a year ago. At the time I assumed it was to do
with shared library support + -betterC, however as time has gone on and more
people reported it, it does not appear to be related.

Typically when ending of debugging (regardless of reason), it tends to take a
long time as well to finish stopping.

As of this writing, I have gotten around to trying to determine the cause of
this problem and have been able to determine it is related to the VisualD
plugin. With it disabled it no longer has these issues.

Originally I had 1.3.1 and then updated to the 1.4.0-beta1, as well as updated
VS 2022, to latest patch, hoping that it would work.

These problems exhibit for both ldc and dmd for all versions I have tried
during this time period.

I've included a screenshot of the "busy" (the busy text isn't there, but
everything else matches) locals window.

I have attempted to remove debug info for both CV4 & CV8 to try and see if that
affects it. I used the pdbutil from LLVM to dump the pdb file, and compared it
against a comparable pdb file produced from clang-cl. However it looks ok.
Funky, but nothing explicitly wrong with what it is generating. This aligns
with a report that remedybg does show locals ok.
