Lock the python-related code with sync.Mutex

$ go get github.com/sbinet/go-python
$ go get github.com/op/go-logging

$ cd src/github.com/spikeekips/embedding-python-in-golang
$ make sync_mutex.go
2014/08/29 20:51:21 python embedding test in golang.
2014/08/29 20:51:21 run inside goroutine
2014/08/29 20:51:21 got json string:
[
  [
    "oldboy",
    "나는 오대수"
  ],
  {
    "I want to eat something alive.": "살아 있는 것을 먹고 싶다.",
    "who are you?": "누구냐, 넌?"
  }
]

2014/08/29 20:51:21 run outside goroutine
2014/08/29 20:51:21 got json string:
[
  [
    "oldboy",
    "나는 오대수"
  ],
  {
    "I want to eat something alive.": "살아 있는 것을 먹고 싶다.",
    "who are you?": "누구냐, 넌?"
  }
]

sync_mutex/main.go just encoding golang data in python and decoding python data in golang. It locks the embed_function using sync.Mutex and embed_function imports json_dump.py using go-python, so simple.

This is json_dump.py,

import json

def run (*a) :
    return json.dumps(a, )

Everything was fine whether goroutine or not.
