Hi,

A customer of our showed some interest in dynamic configuration of SID 
simulations from the point of view of "warming up" the simulator in 
various situations. This generally means limiting high overhead 
functionality (tracing, performance analysis, etc.) to areas of the 
target application which are of greatest interest.

Attached are overviews of external and internal specs of how this could 
be applied to SID along with a patch which implements the spec.

Comments are appreciated and, as always, I'm looking for approval to 
commit this work.

Thanks,
Dave
