应该只有一个位置，但好像可以申请assistant, associate 或者full,如果有3个人分
别申请这3个title,通常来说想申请full prof更加qualified一点，更加有经验一点，
是不是这个人比较容易入围，？

不好意思，有人通过你的网站来捣乱，一口气注册了几万个ID，连着好几天了。
你要愿意配合兄弟把他揪出来，我这就解封。

上面说CPython用的GIL degrades performance.
所以我们使用CPython要避免多线程？

yep...thread implementation of python 2.x sucks..so try to avoid threads.
use multi process for cpu intensive tasks
and async IO or coroutine for io tasks.

not necessary,
think the situation:
you want to hire a full professor, generally you need to give him/her tenure
. how do you know this guy is not a nasty person. consequently, you will
be hesitating to give the tenure directly unless you know the guy very well.
for assistant professor, you will not be that concerned because no tenure
decision involved.

And GIL is still there in CPython 3.1. I hope the problem will be solved
soon.

GIL in CPython is likely to exist forever.

Because python use reference-counting so it would be quite hard to remove
GIL completely.
If you are really care about this issue there are two options:
1: you may try pypy & its experimental module: STM it is said that STM has
already worked with multi cores directly. However it is far away from
production usage.
2: use other implementations like Jython, IronPython or event other
languages..
