FWIW I would consider Chromium a medium sized project...

I'll see if I can grab some sample numbers of a few internal applications.

This seems reasonable to me.  It's worth pointing out though that in
regards to the last comment "IMO it's good to make this lldb-vscode more
general so that it can be used by other debugger frontends besides vscode",
despite the name lldb-vscode, there is actually nothing here that is
specific to VSCode.  It reads DAP requests on stdin and responds with DAP
responses on stdout.  That's literally it.  The only thing vscode specific
about it is the names of the source files and some internal classes.  I
actually wouldn't be opposed to changing it to lldb-dap

[lldb-dev] [8.0.0 Release] rc5 has been tagged

[Hans Wennborg via lldb-dev]

Dear testers,

8.0.0-rc5 was just tagged from the release_80 branch at r355909.

This is identical to rc4 with the addition of r355743. Hopefully it is the
final release candidate, so please give it a good testing.

As usual, please run the test script, share your results, and upload
binaries.

I'll publish source tarballs and docs as soon as possible, and binaries as
they become available.

Thanks for all your help so far, we're almost there :-)

Cheers,
Hans
