99%  ;)   If I understand right, in #commonSend you should be trapping all
common cases, but you will still be missing some of the special selectors
that have special bytecodes associated. Those which are in Smalltalk
specialSelectors. Some will finally delegate to #commonSend so no problem.
Some will not and hence you won't catch them.
You will be missing (I think) those send from #primitivePerform
#primitiveExecuteMethod,  etc..
