// VLDDisable - Disables Visual Leak Detector's memory leak detection at

//    basis. In other words, if you call this function from one thread, then

//    VLDEnable() and VLDDisable(). Without this, calling these two functions
//    unsychronized could result in unpredictable and unintended behavior.
