=> you have an SMP machine, use localhost0, localhost1, ...
- for remote sessions, use ssh multiplexing, this speeds up a dpb
restart by about 1/4 - 1/3
- new option '-s', which starts building in cwd
=> use 'dpb -s' instead of 'make package'
=> mostly useful for SMP machines or if you have your cluster powered
on all the time
- '-b' now forces creation of the dependency file, if it doesn't exist,
it is created automatically
- check signals on returning ssh sessions to notice which ones really
succeeded and which ones where killed
- don't invoke intermediate shells on exec(), allowing to actually kill children
- when we are going down, only kill remaining children, not the whole pgrp
- don't use a SIGCHLD handler, but call waitpid explicitly at the right places
- exit(1) in case of an error
others:
- a little cleanup
- new option -t <timeout>
