Abstract
Lazy loading of executable library objects reduces operating system overhead and memory commitment requirements by postponing object loading until object references are expected. Initial task loading allocates only the main executable and library objects referenced by that executable. Secondary referenced objects are not allocated. Object references cause page faults for allocated but not loaded pages. Page fault handling causes loading and fixup of executable objects. Page fault handling also determines the next level of object references and allocates memory for the next object level. Shared memory systems allow sharing of executable objects until explicitly referenced. Once referenced, memory fault causes copying and fixup to referencing task memory area.
