Heap analysis is nearly impossible without tooling support, and a number of excellent tools are available.
没有工具支持的话，几乎不可能执行堆分析，好在我们有一些优秀的工具可用。
If there is enough space in the heap to satisfy a memory request, it can be handled by the language runtime without kernel involvement.
当堆的空间能够满足程序的内存请求时，那么请求的处理过程就可以直接由语言运行时来负责，而不必有系统内核参与。
In a very similar case, jobs that complete very quickly or allocate very few objects might be able to run without requiring a garbage collection with an appropriate sized heap.
另一种类似情况是，如果作业很快完成或只分配很少的对象，那么只要堆大小适当，作业运行就不需要垃圾收集。
