Creating >100 indexes on my laptop freezes Couchbase Server

Running the "create and build indexes" from mb-36143 resulted in my local Couchbase Server instance completely hanging, so far for many minutes without response.  The UI is spinning on all pages, the 'cbq' binary won't connect, but couchbase-cli seems to return at least some commands correctly.

I can see also that 2 of my 4 CPU cores are at 100% but the other 2 are only at 50%.

I could understand if many hundreds or thousands of indexes cause this issue but at only ~100 I'm hoping we can do something to make the system a bit more responsive...seemingly at this point I would have to revert to scratch or at the very least manually delete the indexes from disk (something the common user likely would not know how to do)

Zip of the log directory attached, I doubt I'll be able to get a cbcollect to run successfully in this state.
