Here's one: https://koji.fedoraproject.org/koji/taskinfo?taskID=101326951
Compared to: https://koji.fedoraproject.org/koji/taskinfo?taskID=101327166

And I suspect this is the cause of the large number of random errors
we've been experiencing with R packages recently. I think that the R
check command has a timeout that is triggered when a ppc64le build
takes too much (specifically when rebuilding package vignettes).
Things seem to have gone back to normal as I noticed them and disabled
vignette rebuilds in most (all?) of them. But these random extreme
delays are annoying, especially in packages with heavy tests.
