Summary:
When scrolling a table or collection view in the Simulator, the Simulator repeatedly freezes with the spinning beachball

Steps to Reproduce:
1. Build a UITableView-based application, with default cell types and minimal data model.
2. Run the app in the Simulator

Expected Results:
Table should scroll smoothly.

Actual Results:
Table scrolls to approx 3/4 of screen height, then freezes. After a few seconds, the beachball appears.  After 10-30 seconds, the beachball will disappear and the table will scroll from where it froze.

Activity Monitor does not show any excessive activity, either from Simulator or any other running process.

Instruments does not show any problems.

Version:
Xcode 7.1 (7B91b)
OS X 10.10.5

Notes:


Configuration:
Occurs consistently in all versions of Xcode 7 since early beta versions.
