Vorbis streams are, to all intents and purposes, gapless.  I suspect that 
any gaps (i.e. unwanted silences) between streams are either present in 
the PCM data presented to the encoder, or you're failing to provide 
vorbis_analysis_wrote() with a zero-length chunk of audio to indicate EOS.

Or, it's a playback problem.

The closest thing I've experienced to what you've described is a minor, 
but audible, waveform discontinuity for quality values of around 3 or 
less, and that only in some pretty pathological cases.
