- affinity info is similar to locks, but with a completely different
lifetime.
- streamline the main loop of the engine, so that it can do two passes:
first pass shuns paths with the wrong affinity. If no good path is found,
those are considered during the second pass.
- make the Core factory aware of what hosts might be running, so that
affinity info for machines removed from a config file will be ignored.
thanks to landry@ for a few tests.
re-enable wait_timeout on localhost temporarily (should be done in another
way, most probably by checking whether repo is on nfs, we can steal code
from VStat.pm)
pass umask through ssh. This took us long enough to figure out, and it's
considerably simpler than tweaking every login class once again.
options on the command line now define *defaults* that host files can
override (for instance -j, stuck, -p, -J).
Add -p /n to mean "take number of jobs, if >1, divide by n, round up to 2,
and use that for parallel.
Document -p.
Make junk be 'by host' (and it's a prop, so you can tweak it).
concurrent log that records how many jobs are running each time it changes.
tag parallel builds *n in the time record.
(it's easy to distinguish between a file and a directory under ports).
expand sequences for those files and hosts
when restarting dpb, kill locks that don't correspond to errors, but to a dpb
running on the same host that's no longer there.
do __WARN__ like __DIE__

document some
- refactor redirect a bit to store multi-line results to a temporary file
- new show-prepare-results stage using that
- prepare and show-prepare-results shouldn't be NoTime, since they're
predictable.
- lock host thru depends -> junk in the junk case.
acquiring the lock is done thru polling in the child, so that it doesn't block
dpb proper.
- new "junk" stage that gathers dependencies and deletes them.
