The slightly unusual parsing in Types.GitConfig avoids the need to look at the remote list to get configs of remotes. annexPrivateRepos combines all the configs, and will only be calculated once, so it's nice and fast. privateUUIDsKnown and regardingPrivateUUID now need to read from the annex mvar, so are not entirely free. But that overhead can be optimised away, as seen in getJournalFileStale. The other call sites didn't seem worth optimising to save a single MVar access. The feature should have impreceptable speed overhead when not being used.
