* HISTORY
* $Log: thread_info.h,v $
* Revision 2.6 89/10/11 14:41:37 dlb
* Add scheduling information.
* [89/05/18 dlb]
*
* Revision 2.5 89/03/09 20:24:12 rpd
* More cleanup.
*
* Revision 2.4 89/02/25 18:41:18 gm0w
* Changes for cleanup.
*
* 4-Mar-88 David Black (dlb) at Carnegie-Mellon University
* Added TH_USAGE_SCALE for cpu_usage field.
*
* 15-Jan-88 David Golub (dbg) at Carnegie-Mellon University
* Changed to generic interface (variable-length array) to allow
* for expansion. Renamed to thread_info.
