When the switchover to the new instruction format happens, what
happens to sys.settrace() tracing? Will it report the same sequence
of line numbers? For a small but important class of program
executions, this is more important than speed.

A simple solution: when tracing is enabled, the new instruction format
will never be executed (and information tracking disabled as well).
What happens if tracing is enabled *during* the execution of the new
instruction format?
Some sort of deoptimisation will be required in order to recover the
correct VM state.
Cheers,
Mark.
