149	Flush windows in context_save_arch() instead of context_restore_arch()	Jakub Jermář	Jakub Jermář	"Gedare Bloom suggests:

  Issue the flushw instruction in context_save_arch instead of context_restore_arch, overwriting the window at cwp with the restored thread state, and ""pretending"" a flushw occurred by setting CANRESTORE to 0 and CANSAVE to NWINDOWS - 2

  The reason I think this would be an improvement is that (1) it  makes more sense to me to flush the windows while saving state, and (2) yousave a register spill and register fill of scheduler()'s window.
