Crash (OOM) on debugging

[segevfiner]

Describe the bug
The extension host crashes on debugging (Another reproduction of #1911). Unfortunately this is a proprietary project so I can't share an immediate reproduction, but I'll share whatever I can that can help pinpoint what causes the crash.

To Reproduce
Steps to reproduce the behavior:

1. Try to debug JavaScript in a project with very large source maps.

Log File

vscode-debugadapter-f7de7273.json

VS Code Version: 1.97.2

Additional context

Thanks, that was quite helpful. @segevfiner wonder if this fixes your use case too.

[segevfiner]

@connor4312 Did it reach the nightly yet? I'll play around and let you know if it happens again.

[connor4312]

It should be on the latest version

@segevfiner - were you able to verify if this was resolved?

[segevfiner]

I didn't encounter this again just yet, but my reproduction was always rather sporadic. I'll open a new issue if I hit the problem again.
