“Manager” is a vague term. Do you mean a replacement for malloc() / free()?
- It handles cyclic pointers so it's really a memory manager.
- It's deterministic because you can predict when all memory blocks will
get deallocated
- All memory allocations are guaranteed to be free when the application
terminates
Is there any documentation or explanation of your implementation?
Yes, in the aforementioned link:
https://svn.boost.org/svn/boost/sandbox/block_ptr/libs/smart_ptr/doc/index.html
Why are you confident that WebKit would see speed improvements using this
library?
I am currently working for a company that uses Webkit and most of the
time the browser hangs because of the current garbage collector.
What about your memory manager indicates that WebKit would be a good choice of
user of it?
Why would Webkit be a good choice? Because it can improve the overall
performance of the Javascript handler.
Are there any other libraries that use it? Which version(s) of Boost is/will
this be included in?
It is still pending for review:
http://www.boost.org/community/review_schedule.html
But it's already been unit tested so it is operative:
https://svn.boost.org/svn/boost/sandbox/block_ptr/libs/smart_ptr/example/
The only thing left to be done is to use a faster pool than the current
Boost one.
Keep in mind that every time a Javascript page terminates, all memory
allocations are guaranteed to be freed instantly. So if the memory is
somehow exhausted; you just have to reload the page.

Greetings,
I wrote a deterministic memory manager in C++ and I was wondering if their is
any interests introducing it into Webkit, thus speeding up Webkit.
The memory manager is located here:
