--- Comment #1 from Takashi Komori <Takashi.Komori at sony.com> ---
CurlRequestScheduler uses CURL pointer as job identifier, but libcurl sometimes re-use released pointer.
Therefore depending on timing, finalizeTransfer might be called more than once.

1)One CurlRequest (request A) is canceled and releases CURL* (pointer P).
2)And another CurlRequest is created (request B) and gets re-used CURL* (pointer P) same to former .
3)CurlRequestScheduler does finalize task for request A using pointer P.
4)When request B is closed, CurlRequestScheduler does finalize task using same pointer P and issue occurs.

Scheduler has to control tasks by CurlRequest* instead of CURL*.
