.intro: The ANSI fake VM is an implementation of the MPS VM interface (see design.mps.vm) using services provided by the ANSI C Library (standard.ansic.7) -- malloc() and free(), as it happens.
.align: The VM is aligned to VMAN_ALIGN (defined in impl.h.mpmconf) by adding VMAN_ALIGN to the requested size, allocating a block that large using malloc(), then rounding the pointer to the base of the block. vm->base is the aligned pointer, vm->block is the pointer returned by malloc(), which is used in VMDestroy().
