Steps to reproduce:
1. Add at least two markers that are far apart from each other (for example, one in the US and one in Australia).
2. Use a custom icon with custom scaling for those two markers (using the scaledSize parameter of MarkerImage).
3. Set the zoom level to 15 or closer.
4. Load this map in Chrome on OS X.

The map will take too long to load, and may crash. If it does load eventually, zooming in to a marker will cause it to crash. Sometimes panning the map around will also cause a crash or very poor performance.

This bug appeared in the last week or two, and does not appear in 3.4.

Sample code:
Version 3.5 (latest stable) showing the bug: http://lib.concept3d.com/web/maps/markers/
Same code with 3.4 (no bug, works fine): http://lib.concept3d.com/web/maps/markers/index2.php

System info:
Macbook Air, 1.4ghz Core 2 Duo, 4GB RAM
Mac OS X 10.6.6 (also tested on Lion, same issue)
Chrome 13.0.782.112
