It was because any object could have a dependent (even if model was favored) so for object the registration was stored in a large table. >> I hope we don't replicate this scheme, I had understood Announcements >> did not thanks to explicit subscription. >> Anyway, a bit of archeology is always helpfull when cleaning >> Smalltalk... >> > > It is strange, i have a feeling that people think i am being > short-sighted or don't understand things, > while i'm trying to show the potentional bottlenecks of Announcements > framework itself... no continue I like to see arguments.

[Pharo-project] Hash changes, take 2

by Andres Valloud

Hello, Here are the latest hash changes. It was easier for me to introduce basicIdentityHash on top of the changes I had done for scaledIdentityHash. I hope you don't mind. Also, note I had to change some senders of identityHash. Martin et al, would you mind reviewing these? After I wrote the code, I began feeling changing identityHash may not be what we want in general... Andres.

Hello, While working on hashing, I wrote this bit of new code to speed up some of the tools. I hope I didn't make a mistake... it seems to me it should work fine. Enjoy! Andres.
