One instance, and emacsclient.

Sorry to be late.

Emacs was running as daemon and I had to edit new file with
emacsclient. However, Emacs was busy doing something else in this case
video playing by using `!' so the instance was blocked. Then when
video was interrupted, Emacs crushed completely in the memory.
