Ok, in fact we are using the api correctly, creating a new FeatureStore
on every request and passing a thread-local transaction to it (sorry for
the confusion).
Despite that we still get this error occasionally:
Caused by: java.lang.IllegalArgumentException: Transaction already has
an entry for key:110m_populated_places_simple. Please check for existing
State before creating your own.

After digging a bit further, i reformulated my problem (and a
possible solution) here:
http://jira.codehaus.org/browse/GEOT-4388
The main issue is that ContentFeatureSource itself is evidently
not thread-safe (and not claiming to be), but could perhaps be
with some modification ?
Not it's meant to be, see my comment in the issue. If you are sharing
a FeatureStore among threads you're misusing the API.
Cheers
