Resolving is retried in increasing intervals (maximum is one hour)
until it succeeds or fails with a non-temporary error.
Unresolved sources are included in the activity report as offline
sources and the online command can be used to retry it immediately.
This could be improved by resolving in a separate thread/process
to avoid blocking.
None of the current handlers really need it and with temperature
compensation enabled it would be necessary to undo the compensation
before passing it to the handlers.
This is a verbatim copy of the files at that stage of the repository that was
built from the CVS import. It allows future development to see a bit of recent
history, but without carrying around the baggage going back to 1997. If that
is really required, git grafts can be used.
