[pypy-dev] Questions for Armin

My long posts were intended, in part, to expose my assumptions for
correction if needed.
Here are what I conceive to be the key questions about psyco:
1. How often and under what circumstances does psyco_compatible get called?
My _guess_ is that it gets called once per every invocation of every
"psycotic" function (function optimized by psyco). Is this correct?
2. True or false: the call to psyco_compatible would be equivalent to
runtime code that discovers special values of certain particular variables.
3. True or false: adding more state information to psyco (in order to
discover more runtime values) will slow down psyco_compatible.
4. Are these the most important questions to ask about psyco? If not, what
_are_ the key questions?
Thanks very much.
Edward
