could you re-run the scenario with GIT_TRACE2_PERF=1 which will
give the full Git process stack as we reach that rev-list call.

Sorry about the delay, I've been trying to reproduce... reproduceably :)

I now have a whole file of examples and observations, attached (I
assume text attachments are allowed on this mailing list?), which
should be reproducible for anyone as I was able to use the linux
kernel repo to illustrate all cases.

I appreciate that you took so much time to investigate here. You
have convinced me that there are deeper things going on than just
the "unshallow, but with filters this time" situation.

I have created an internal issue for my team to investigate this
when we have capacity for it. I don't think it will happen this
month, so if anyone else has the time now then don't wait for us.

Thanks,
