This function was noticeably lagging the main thread while caching. The cause was OpenEXR's internal thread pool competing with our main thread. Since we have our own system of worker threads, its thread pool was unnecessary for caching, however for normal playback it was a useful optimization. Unfortunately OIIO (which we were using to save EXRs) didn't provide quite enough control over OpenEXR's threading behavior (only providing control for over the global thread pool and not on a per-image basis), so for caching we've switched to using OpenEXR directly. This has noticeably sped up the main thread while causing no noticeable slowdown to the caching process.
