The analyzers do not request the stop, the configuration does. The analyzers 
(should and mostly do) ask the configuration 'should we continue?' at 
reasonable intervals. On the strigi side, different behaviors can be handled, 
but the they have to be specified. Do you want only titles? Possible. Do you 
want a hard limit on the length to read? Also possible. Do you want to read up 
to X for this and up to Y for that field? Not pretty but possible. Do you want 
a time limit on the analysis? That is possible too. Just derive from 
AnalysisConfiguration and reimplement virtual bool indexMore() const.
