40	Memory management default callbacks	Eric.VanAlst@…	eugene	"In the SDR Rev. 01, paragraph 2.1.5 states, ""The defaults for each of these 
callbacks is NULL,"".  In the next paragraph 2.1.5.1 states, ""the default 
callback function(psMemExhaustedCallback) immediately returns NULL.""

Is it desired to have these function pointers point to NULL initially and have 
the user use the psCallbackSet routines to point to their callback functions or 
should PSLib supply default callback functions that return with out doing 
anything as in paragraph 2.1.5.1?

A problem could occur if callback event occurs without the user specifying a 
callback function and there is no default callback function."	defect	closed	normal		PSLib SDRS	unspecified	minor	fixed
