Based on my experience it should really be a correlation of temperature
rate of change vs. jitter.  On my self-ovenized servers I see on average
around 200ns jitter (close to the theoretical limit of 157ns based on
the 19.2MHz clock) with the occasional peak to about three times the
baseline.

====================================

Achim,

I didn't write the part you quoted - blame my non-standard emailer!

What I see on the RPi is a change of offset against rate of change of 
temperature - non-ovened.  It's just as I expect.

Cheers,
David
