Cumulative count of heap allocations whose storage was freed
		by the garbage collector. Note that this does not include tiny
		objects as defined by /gc/heap/tiny/allocs:objects, only tiny
		blocks.

	/gc/heap/goal:bytes
		Heap size target for the end of the GC cycle.

	/gc/heap/live:bytes
		Heap memory occupied by live objects that were marked by the
		previous GC.

//
// 1. shade(*slot) prevents a mutator from hiding an object by moving
// the sole pointer to it from the heap to its stack. If it attempts
// to unlink an object from the heap, this will shade it.
//
// 2. shade(ptr) prevents a mutator from hiding an object by moving
// the sole pointer to it from its stack into a black object in the
// heap. If it attempts to install the pointer into a black object,
// this will shade it.

// # Heap profile
//
// The heap profile reports statistics as of the most recently completed
// garbage collection; it elides more recent allocation to avoid skewing
// the profile away from live data and toward garbage.
// If there has been no garbage collection at all, the heap profile reports
// all known allocations. This exception helps mainly in programs running

Daemons use the JVM's default minimum heap size.

If the requested build environment does not specify a maximum heap size, the Daemon uses up to 512MB of heap.
512MB is adequate for most builds.
Larger builds with hundreds of subprojects, configuration, and source code may benefit from a larger heap size.
