In sbuild I was working around it by explicitly flushing the output
stream.  I've tested by commenting out the explicit flushing and doing
a few builds.  Output does not appear to be unduly buffered, so it's
possible that this issue has been resolved somehow.  However, the
perl code has changed slightly in the meantime, and I'm now using a
newer system, so it's possible that isn't simply not manifesting with
the setup I have.  There's certainly no lag/choppiness in the live
build output.

In the absence of being able to reproduce with the code which previously
demonstrated the problem, I'd say this could be closed.  If anyone can
properly reproduce it, it can be reopened.

Roger
