Memory Leak (Process Heap) Pattern

We continue our modeling of software behaviour with the ubiquitous Memory Leak (process heap) pattern (Volume 1, page 356). Instead of leaking small heap allocations that are easy to debug with user mode stack trace database our model program leaks large heap allocations (Volume 2, page 137):

int _tmain(int argc, _TCHAR* argv[])
{
 // create extra 25 heaps initially
 for (int i = 0; i < 25; ++i)
  HeapCreate(0, 0, 0);

 // create a heap to leak within
 HANDLE hHeap = HeapCreate(0, 0, 0);

 while (true)
 {
  HeapAlloc(hHeap, 0, 1024*1024);
  Sleep(1000);
 }

 return 0;
