(2) is not true, because dlopen uses mmap, and mmap uses lazy loading for 
parts that are "loaded" in read-only mode. This is regardless of RTLD_LAZY 
vs RTLD_NOW: those flags are about symbol resolution; actual inclusion of 
the file into the process's memory is done using CPU-level virtual memory 
and the kernel's disk-cache.

(What I say is the case on at least Linux and OSX; can't quite speak for 
MS)
