Hi Marc,
Yes, I've confirmed the issue is with training the SVM classifier as part of
the overall ensemble of internal classifiers in the face classifier when you
have over 100,000 confirmed faces.

There's good news and bad news. The good news is the face classifier "falls
back" to less efficient approach while the SVM is being trained, so face
recognition is usable while it's happening.

The bad news is there's no way to fix this without rewriting the entire face
classifier.  I'll add rewriting the face classifier to eliminate the the SVM
classifier to my 8.8.0 to-do list.

Cheers,
Mike
