==================== Summary ====================
Name: Kernel-ul.1014
Author: ul

UUID: 7be073b0-6c2b-461d-a836-3031dc02743d
Ancestors: Kernel-mt.1013
- before doing a full GC, try an incremental one when primitive 71 fails. This is expected to reduce the number of full GCs when large chunks of memory are being allocated repeatedly

handleFailingBasicNew
"handleFailingBasicNew gets sent after basicNew has failed and allowed
a scavenging garbage collection to occur. The scavenging collection
will have happened as the VM is activating the (failing) basicNew. If
handleFailingBasicNew fails then the scavenge failed to reclaim sufficient
space and a global garbage collection is required. Retry after garbage
collecting and growing memory if necessary.
Primitive. Answer an instance of this class with the number of indexable
variables specified by the argument, sizeRequested. Fail if this class is not
indexable or if the argument is not a positive Integer, or if there is not
enough memory available. Essential. See Object documentation whatIsAPrimitive."
