Invalidate the FontCache on WebProcess suspension / critical memory pressure to free a bit more memory (an extra 4-16Kb on the pages I tested). We already purge inactive font data on non-critical memory warning but invalidating the whole FontCache takes care of clearing the FontCascade cache and the fontPlatformData cache as well.
