We do that all the time when developing software.

Of course you don't. As I said in my earlier posting, I'm all in for people that know their job and do good work. But this thread is about automated memory management and you seem to generally dislike features like this while I tried to point out that they can actually work by pointing at the JVM example. The fact (?) that Linux MM is not as good as it could be does not prove that automation like this is bad in general.

I am sure you can find benchmarks that prove each claim - Perl being faster and Java being faster.
