StatTraq working for WP 2.01?

I have upgraded to WP 2.01 and I have kept StatTraq active. It seems to work fine, but on some occasions I get problems with MySQL being overloaded when I save posts or comments. I am not sure if this has anything to do with my WP installation or if it is some other user at my web host that has a bad script.

Are there known problems with StatTraq and WP2? I have searched the support forums without finding anything relevant yet. (Yes, I know that StatTraq is not listed as compatible with WP2, but I have not seen an explanation as to why or what could go wrong if it is used.)
