I do the same thing with spamassassin but utilizing 4-folders:

spam
spam-learn
spam-probably
spam-unlearn

where spamassassin drops potential spam in spam-probabaly. I look through it
and move what is spam to spam-learn (where it is processed by sa-learn and
moved to spam automatically) and move what isn't spam to spam-unlearn where
unlearn is run on it and it is put back in the inbox.

The key here, and in your case, the movement of mail between folders should
not be causing a reindexing of your entire mail store. If that is what is
happening, then that is the bug that should be looked at and confirmed.
