Re^2: Timing of garbage collectionby BrowserUk (Pope)

Perl doesn't have "garbage collection" in the sense that it never gives memory back to the OS.
That's demonstrably not exactly true:
That shows that perl allocating a 2MB scalar and then returning that 2MB back to the OS.
On my Perl/system, the break point for the size of allocations that are released back to the system is 1040351 bytes. anything more and it is; less and it is not:
That number is a around 8k less than 1MB, so presumably it is 1MB internally but then some is used for internal management.
With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
