Users can get out of the deadlock by canceling the update job of the type histroy.
The problem is that the history joins the update job while holding a lock which the update job wants to aquire.
Fixed for build >= I20060117.
Verified in I20060214-0010 through code inspection in OpenTypeHistory to which TypeInfoHistory has been renamed.
