Searching in large project for any common term makes the IDE unusable for a few minutes

Hello,

I know that there is protection against large number of search results, and I was getting the warning about VM memory consumption, so some base is covered already, but it's still very annoying when the simple project wide search grinds the IDE down for a few minutes

Could you please provider memory snapshot taken during this operation? Instructions can be found at: http://www.jetbrains.net/devnet/docs/DOC-1144

Regards,
Oleg
