The key to this optimization is that by delaying the allocation of physical blocks until they need to be written to the disk, more blocks are present to allocate and write in contiguous blocks.
这种优化的关键是延迟物理块的分配,直到需要在磁盘上写这些物理块时才对其进行分配并写到相邻的块。

The first is a general-purpose allocation and can serve requests for any number of contiguous chunks.
第一个分配程序是通用分配,可以满足针对任何数量的连续内存块的请求。

This entry lets us know that there was an allocation failure, which presents itself when there is not enough contiguous space in the heap to allocate the object.
