Subject: Re: 5.5.0-0.rc1 hang, could be zstd compression related

OK this is interesting. It took 7 hours to hit it the first time. And
the consistent reproducer I've now run into twice, is 'dnf install'
any little rpm, which is what I was doing the first time I hit it. I'm
not sure what about dnf or rpm is triggering this,  I've got other
things doing a bunch of small file writes including Firefox - yet
those don't trigger it.

Next, I tried a couple more times with compression disabled, and the
problem doesn't happen. So it does seem zstd related. Maybe.
