Actually, it's not just that - it also slows down opening the layer
properties window for a WMS layer as the capabilities is requested
once again.

For reference I have a commonly-used WMS where the capabilities
request is 9MB. Understandably, this is a significant issue with QGIS
using this layer! I've learnt to live with it, but a cache would be
VERY much appreciated.
