SYSMEM -- System Memory Interface


	1) Usage

	| OBJECT smem[sysmem];

	The sysmem class provides an interface to the malloc(), free(),
	and realloc() functions of the C library on Unix systems. The
	class itself has no state other than that stored in the C
	library. Hence a single instance per program is sufficient.

	For details on LIBC memory management, consult the malloc(3),
	realloc(3), and free(3) manual pages of your local system.


	2) Methods


	2.1 MALLOC

	| SMEM.MALLOC(size) ! Num => Vec

	Allocate a vector using malloc() and return it. A return value
	of zero indicates failure.


	2.2 FREE

	| SMEM.FREE(vec) ! Vec => 0

	Release a vector to the free memory pool using free().


	2.3 REALLOC

	| SMEM.REALLOC(vec, size) ! Vec,Num => Vec

	Re-allocate a vector with a new size using realloc().
