To my surprise new operator does not return NULL on error. It seems to throw an exception. When did this happen?

In Visual C++ 2005, the C Runtime Library's new function will also throw a std::bad_alloc
exception if the memory allocation fails.

If you still want the non-throwing version of new for the C Runtime Library, link your program
with nothrownew.obj. However, when you link with nothrownew.obj, new in the Standard C++
Library will no longer function."

2. Is new a thread safe operator? What if I'm using some libraries that most likely use malloc. Is memory allocation still thread safe? I'm using dynamic link run time for my program and hopefully all the libraries. If some library is using a different run-time but I don't free its memory is that fine?

3. What is the memory allocation limit for a process in Windows XP? Is it 2 GB? Or RAM + swap space?
