This article discusses the limitations that exist when allocating memory
handles.
The minimum block you can reserve with each call to VirtualAlloc() is 64K.
It is a good idea to confirm this number by checking the allocation
granularity returned by GetSystemInfo().
With HeapAlloc(), there is no limit to the number of handles that can be
allocated. GlobalAlloc() and LocalAlloc() (combined) are limited to 65536
total handles for GMEM_MOVEABLE and LMEM_MOVEABLE memory per process. Note
that this limitation does not apply to GMEM_FIXED or LMEM_FIXED memory.
