Issue 2:
Describe what you were doing when the bug occurred:

Profiling a slow component

In a component that rendered 5000 pre tags with single lines of text in them, that has an unrelated controlled text box is the same component that was typed into while profiling. App hung a while and, when it rendered again the error was in the profiler.
