Deferred coalescing
Web2) Deferreds used in argument defaults have to be re-deferred every time the function is called, to avoid coalescing to the exact same object every time. 3) And then you still have to do "n=n" at the start of the function to un-defer it.

My question is can we optimize current RC using strategies like Deferred RC and Coalescing? If no then where would I face problem if I try to implement these sorts of strategies? These strategies all depend …
Webdeferred coalescing will improve throughput because not coalescing will enable more time for malloc and free requests to complete. Peak memory utilization is the sum of payload sizes divided by the heap size. The more fragmentation there is, the larger the heap size will need to be, resulting in a smaller peak ...
