Should I put a try-finally block after every Object.Create?

Question

I have a general question about best practice in OO Delphi. Currently, I put try-finally blocks anywhere I create an object to free that object after usage (to avoid memory leak

Last year at Delphi Developer days I saw some of Marco Cantu's private stash of code and he calls try finally every single time he creates anything.

Somebody asked him about it, and he said he tries to do it all the time.

But it's especially a good idea for multi-threaded code when it comes to entering and exiting critical sections, although that's not on the topic, it's a good thing to remember.

Obviously sometimes it's a bit obtrusive and if it's not in the culture of your work environment to be spot-on in your robsutness it may make you look like a goodie-two-shoes. But I think it's a good idea. It's kind of like Delphi's attempt at enforced manual garbage collection.
