abstract
开篇揭示了concurrent programs的存在，写出正确的concurrent programs需要很多点：包括concurrency bug detection, concurrent program testing, concurrent programming model design。
作者提出这篇文章是第一篇（在作者的知识范围内）综合现实世界并发错误特征的一篇study，（我自己的工作也可以这么说，是研究uaf-patch的第一篇）。仔细调查并发bug的模式，从4个有代表性的服务器和客户端应用中（MySQL, Apache, Mozilla and OpenOffice）随机选择105个策略。作者提出：Our study reveals several interesting findings and provides useful guidance for concurrency bug detection, testing, and concurrent programming language design.（可以作为我们的论文的结果。
然后作者列出自己的findings：
(1) Around one third of the examined non-deadlock concurrency bugs are caused by violation to programmers’ order intentions, which may not be easily expressed via synchronization primitives like locks and transactional memories;
(2) Around 34% of the examined non-deadlock co
