 In VS 2012 it is mandatory to increase the default stack size of 1 MB to
 at least 2 MB due to implementation of std::map intermittently requiring
-substantial amount of stack and causing stack overflow. ZeroMQ generally
-needs more stack when FD_SETSIZE is higher.
-In all Windows builds it is recommended to start with at least 2 MB stack
-size unless application using ZeroMQ is using large number of threads which
-can cause substantial consumption of virtual address space, especially if
-32 bit build is used.
-Generally, programmer needs to tune the stack to balance memory consumption
-but never get into situation that stack is overflown.
