            Bug ID: 32435
           Summary: std::deque default block size (4096) is too generous
           Product: libc++
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: All Bugs
          Assignee: unassignedclangbugs at nondot.org

I profiled STL containers in Chrome on Android and found that std::deque
(std::queue, std::stack) wastes considerable amount of memory because of its
4096-byte block size. I'm proposing changing block size to 512 bytes and min
block length to 1.
