Thanks @dan-blanchard ,
I experimented about python's GIL just now, and with python 2.7.6 in OSX I
found that other thread can hold CPU more than 1 sec when timer is expired at
that time.

Actually I wasn't affected this issue during I was working with Python
cause it was I/O intensive job, and seems like it isn't same to CPU intensive
job.
Default tick time is somewhat very long. I found one document which says
tick time is about ~6.5 secs, which doesn't meet our requirement.
GIL is a major problem, and maybe I should check it with Ruby.
