Please show me details and describe exactly where you found this.

I understand that I'm asking for something that might not be easy to create,
but it is even harder for us outside of your project to understand or
reproduce this issue.

Until we can reproduce or understand it, it *could* also just be your program
running amok somehow. libcurl is after all used by a large amount of users all
over that don't get this problem.

Also the only thread doing libcurl calls?
