Stylistically, we tend to do:
import signal
signal.signal(signal.SIGPIPE, signal.SIG_DFL)
so I've a small preference for that. I discussed this with Paul and we
think other bitbake tools may also have this issue. We wondered if it
was possible to do something more centrally in bitbake, and/or fix the
other tools at the same time.
Any thoughts on that?
Cheers,
Richard
