Expressions still get evaluated even though the task isn't executed

Whilst investigating the problem talked about here: http://forums.microsoft.com/msdn/ShowPost.aspx?PostID=118141
I noticed something quite strange.

The symptom of whatever problem we are having (we don't know yet) is that some property expressions fail to get evaluated and cause the package to fail. ALL of these property expressions are in package-scoped eventhandlers.

Now, if I set DisableEventHandlers=TRUE on the package container the problems still occur. If I completely delete the eventhandlers the problem goes away.

So, it seems to me that even though DisableEventHandlers=TRUE, the property expressions within those eventhandlers are still evaluated.

Why is that? Its pointless to evaluate property expressions if they are not going to be used - it means the package is doing unnecassary work.
