Middleman server does not respond to SIGINT or SIGTERM while live reloading

[FriedSock]

If I perform a search and replace while live reloading is turned on, the middleman server will take a long time performing all its live reloading. At the moment my only option is to kill -9 the process and start the server again.

Gemfile.lock please

I've got the issue that after about 3 times editing a sass file, middleman server hangs and I can only kill -9. It's worse when more than 1 browsers are connected.
