Extending the Sys.sleep value to 3.5 on line 142 in the unpackPkgZip function works manually via

trace(utils:::unpackPkgZip, edit=TRUE)

However, it can also be done programmatically by running the following before install.packages:

localUnpackPkgZip <- utils:::unpackPkgZip
body(localUnpackPkgZip)[[14]][[4]][[4]][[4]][[3]][[3]][[2]][[2]] <- substitute(3.5)
assignInNamespace("unpackPkgZip", localUnpackPkgZip, "utils")

This must be run every time you have a new session. You can run it multiple times in the same session without issue.
