With 23.0.0 we have even less memory available which is causing the browser (openWeb) and eshop (systemWeb) applets to crash immediately. While the amount of memory required by the browser applets didn't change this time, just implementing 23.0.0 changes was enough to push it over the limit. Instead of reducing the memory available to us even further, this convoluted set of patches attempts to reclaim around 9 MB of unused browser memory.
