Stop hanging command execution in console

[0xless]

I'm trying to automate the attack to a whole network and I'm using client.consoles.console(cid).write(command) to execute commands in a metasploit console.

I found that an exploit I'm using sometimes hangs and blocks the execution of the whole process.
What I need to do is to stop the execution of this command (without destroying the console).

I couldn't find a way to do this using the library. It would be a cool feature to have.

I thought about sending a SIGINT signal to take care of that but I struggle to figure out the process to which send the signal.
