花了几个钟头研(goo)究(gle)了一下为毛Python要留着GIL不改掉,作为一个非CS人感
觉自己的智商好不够用...总结如下:1.5时代去掉GIL以后和没有去掉GIL比较,由于大
量的lock calls,单线程速度大幅度下降,而对于纯python的应用范围内这显得得不偿
失。所以,权衡的结果,是在纯python的时候用多进程取代多线程,同时在更低层次上
需要用多进程的时候,利用c-extensions来实现多线程操作。
不知道大家咋想?

第二十一条ARTICLE 21 (Other Income)
一、缔约国一方居民的各项所得,不论在什么地方发生,凡本协定上述各条未作规
定,应仅在该缔约国征税。
1. Items of income of a resident of a Contracting State, wherever arising,
not dealt with in the foregoing Articles of this Agreement shall be taxable
only in that Contracting State.
二、第六条第二款规定的不动产所得以外的其它所得,如果所得的收款人是缔约国
一方居民,通过设在缔约国另一方的常设机构在该缔约国另一方进行营业,或者通过设
在该缔约国另一方的固定基地在该缔约国另一方从事独立个人劳务,据以支付所得的权
利或财产与该常设机构或固定基地有实际联系,不适用第一款的规定。在这种情况下,
应视具体情况适用第七条或第十三条的规定。
2. The provisions of paragraph 1 shall not apply to income other than that
from real property as defined in paragraph 2 of Article 6 if the recipient
of such income, being a resident of a Contracting State, carries on business
in the other Contracting State through a permanent establishment situated
therein, or performs in that other Contracting State independent personal
services from a fixed base situated therein, and the right or property in
respect of which the income is paid is effectively connected with such
permanent establishment or fixed base. In such case the provisions of
Article 7 or 13, as the case may be, shall apply.
三、虽有第一款和第二款的规定,缔约国一方居民的各项所得,凡本协定上述各条
未作规定,而发生在缔约国另一方的,可以在该缔约国另一方征税。
3. Notwithstanding the provisions of paragraphs 1 and 2, items of income of
a resident of a Contracting State not dealt with in the foregoing Articles
of this Agreement and arising in the other Contracting State may also be
taxed in that other Contracting State.

大致如此。主要原因之一是基于引用计数的垃圾回收,
CPython代码里很多Py_INCREF和Py_DECREF的macros,
去掉GIL之后这些引用计数操作就不是线程安全的了。
所以在每个线程装个大锁,实现bytecode级别的线程安全。

所以都是ref counting惹的祸啊…搜了一转,大多说是因为在早期的时候GC远没现在这
么成熟,ref counting的方法又简单,就用了;哪儿想到这么多年以后多核运算这么普
及…
早在py3k开发时期有人问Guido说,能把这个ref counting换掉吗?答复说,那所有
code都重写,改动太大了…就只得作罢。
历史残留问题真是处处都有啊,嘿嘿。

As far as I know, refcnt is a major reason, but not the whole story.
Python (as well as Ruby) VM bytecodes are simply way too high level
for any finer-grain locks to be useful.
PyPy, another Python implementation that trace-JITs the interpreter
itself instead of the Python program, does not support refcnt semantics
--it uses multiple gc algorithms, with minimark being the default one--
but it still has GIL present, for many reasons.
You may take a look at their STM proposal to get some ideas

When cooking with olive oil, save your extra-virgin expensive oils for
salads, dressings, and vinaigrettes. You can also drizzle it over slices of
crusty bread or onto open-face sandwiches. Use it on a baked potato or add
it to mashed potatoes instead of butter. Extra virgin olive oil tastes great
on cooked vegetables or brushed onto fish or meat before serving.
When sautéing or frying, use either a combination olive oil (one that is
simply a blend of extra virgin and regular olive oil) or a str
