Composing High-Performance Memory Allocators 编写高性能内存分配器
This was due to characteristics of the memory allocators on the systems I was running on (mainly the then-current versions of SunOs and BSD ).
这是由我用来运行这些C++程序的系统（主要是早期版本的SunOS和BSD）上的内存分配器的特性决定的。
These papers find that versions of this malloc increasingly rank as simultaneously among the most time - and space-efficient memory allocators available.
这些论文发现在现存的大部分时间和空间高效的分配器中，这个版本的malloc被越来越多的分类为同时具备这两种特点的。
However, allocators should provide some means for detecting corruption due to overwriting memory, multiple frees, and so on.
尽管如此，分配器应该提供一些方法探测由于改写内存，多次释放等等这样的错误导致的内存混乱。
