They run the action and potentially retry running it with some +configurable delay for a configurable number of times. The purpose is +to make it easier to work with IO and especially network IO actions +that often experience temporary failure and warrant retrying of the +original action. For example, a database query may time out for a +while, in which case we should hang back for a bit and retry the query +instead of simply raising an exception. + +After uninstalling, run this command to unregister the package from +the ghc package database: ghc-pkg recache |
