There's also another problem: the store used to cache the stylesheets
apparently tries to serialize the cached items to disk, as reported
here:
http://marc.theaimsgroup.com/?l=xml-cocoon-dev&m=106969948018306&w=2

just had a quick look into it, it seems that if we would set the
use-persistent-cache option of the transient store to false this should
be fixed. I don't know if this would be acceptable though (depends on
which other components put items in that store).
