Interrupts in integrated terminal

[tom-programming]

Issue Type: Bug

1 Use Linux system. Open the integrated terminal and run "yes". I am assuming that the experience on the integrated terminal should be the same as with a regular terminal

2 Ctrl - C should send a SIGINT and stop the process. It doesn't (but it works somehow in "top")
3 Ctrl-\ should send a SIGQUIT and stop the process with a core dump, but it is masked by a keyboard shortcut that creates a new terminal tab. Even removing this shortcut no signal is sent (again it appears that it works in "top")

OS version: Linux x64 4.4.0-121-generic

Depending on your hardware yes could run faster than the parser. Luckily a community contribution is currently in progress to boost the speed of the parser which should improve the situation xtermjs/xterm.js#1399
