The wiki docs on the _changes feed say that "A continuous feed stays =

However, what I=92m seeing is that after 60 seconds an entry with a =

I=92m guessing that, contrary to the docs, there is a default timeout in =
continuous mode, and I=92ll have to add something like =
=93&timeout=3D9999999999=94 to the URL to defeat this?

(This is the 1.1.1 CouchBase Server Community Edition, on Mac OS X =
10.6.7.)
