signal module doesn't have pause method in Python 2.7 for Windows

Traceback (most recent call last):

Yeah, this is a known bug, I thought this was fixed a while ago. Are you using sulley from the google code svn or from the master repo here?

[jimmers]

I got code via:

git clone https://github.com/OpenRCE/sulley.git

On each fuzzer run I get an exception about pause method missing since I'm running Sulley on Windows.

That's odd, I've never run into that issue myself...

I also meet the problem .on win7 git clone sulley form github.

I've also ran into this problem.
The cause is that the "signal" module on Windows does not implement the "pause()" method:

Is there any solution about this issue? My system is win7 64bits.

I made a pull request but what worked for me is to catch the exception and loop instead:
