title: Thread-safe TBB scalable allocator
body: <p>Recently I switched from system memory management (malloc/free) to Intel's TBB scalable allocator. The problem is I cannot find any info if it's thread-safe. Whole TBB is built around threads, so it would seem logical, but without concrete evidence, I do not want to assume such things. Yet, I do not want to make any unnecessary synchronization either. Does anyone have some info on this?</p>
