# Todo
## Extra
Add support for multiple clients at the same time
server
	client pings server every 100 msecs, and only starts writing after receiving SIGUSR2 back
	client sends \0 when done
server
	server waits for a signal when pid = 1
	when server receives signal it sets the pid to the sender pid
	it keeps ignoring signals from other PIDs untill it received \0 from the current pid
	after \0 is received pid is set back to 1
