That is one way of looking at it. More accurately 15 is SIGTERM which attempts to terminate a process using its normal shutdown routines. 9 is SIGKILL which abruptly ends the process with no graceful exit routines called. Usually if a process has gone off the rails you've no choice but to kill it. I don't even waste my time typing kill -15 anymore. I mean if the process was behaving I wouldn't be trying to kill it!
To make this post useful people should be aware that X Window has its own process killing mechanism called:
xkill
It turns your cursor into a skull and crossbones, which is pretty cool, then you simply click on the offending window with your Jolly Rodger cursor and end it.
$ man xkill
For more information.
