I would expect not. What if you'd passed a pointer to that memory to another program (perhaps your caller) before returning? It's usually these what-if situations that make memory leaks so difficult to prevent. 

Come to think of it... Can I save a pointer to memory in a userspace? And if so, is that pointer valid in another job? If so, can I even rely on an endjob to reclaim the memory?

I'm not an expert on such things ... but wouldn't the memory be 
recovered when the program ends since *INLR is on?
