// these fields used to spread all over the place, because they must be used in 3 ways:
//  - they must be defined somewhere
//  - they have an #ifdef to get a shorter name
//  - they must be initialised somewhere
//  - they may be of interest to restore
//
// The defs include 3+ components:
//   Type
//   name in structured / global name 
//   init code (optional)
//   restore code (optional)
//
// Stuff that must be shared by all threads or workers
