Seeing stdout/stderr from children

[yang]

I currently have Spawning spin up a bunch of Pastes, but I can't get any of their stdout/stderr. Can Spawning either simply let the stdout/stderr pass through (to its own stdout/stderr), and/or can Spawning direct each child's stream to its own file?

Clarification: stdout/stderr work, but the default Paste logging facility - which prints to stderr - isn't able to produce any visible output. Currently hack: a new config_factory that redirects stdout/stderr to per-child log files.
