Exception when timer measures for too long

[akhomchenko]

Good day.

Sorry for my bad English.

I've installed metrology and next sample script fails:

#!/usr/bin/env python
#coding: utf-8

import time
import logging

from metrology import Metrology

timer = Metrology.timer('do_it_timer')

if __name__ == '__main__':
    with timer:
        time.sleep(15)
    print timer.mean

With an exception:

Traceback (most recent call last):
  File "metrology-sample.py", line 16, in <module>
    time.sleep(15)
  File "/home/vagrant/src/metrology-sample/venv/local/lib/python2.7/site-packages/metrology/instruments/timer.py", line 40, in __exit__
    self.update(duration)

    return self.compare_and_set(expect_value, new_value)
  File "/home/vagrant/src/metrology-sample/venv/local/lib/python2.7/site-packages/atomic/__init__.py", line 86, in compare_and_set
    return bool(atomic.long_compare_and_set(self._value, ffi.new('long *', expect_value), new_value))
TypeError: an integer is required

Is it ok?

BTW https://github.com/cyberdelia/metrology/blob/master/tests/instruments/test_timer.py#L18 will fail too if you'll increase sleep time.

Thanks for the report! I fixed in, and released metrology 0.10.1.
