Changing a list schema in a feature requires IIS reset to take effect

This is more a note to myself than anything smart I have to say:
When you build a list definition, and deploy it as a feature, if you make a change to the schema, the change will not take effect until you do IISRESET.
Deactivating the feature and uninstalling it, then installing it and activating it will not do the trick - you must either recycle the application pool or do IISReset.
