The --once argument clears the display

[GoogleCodeExporter]

Enhancement.

What steps will reproduce?
1. jvmtop.sh --once <pid>

What is the expected output? What do you see instead?
When running a monitoring program like top once, the screen doesn't clear 
before displaying output, the results simply appends to existing location in 
the window.  This allows me to see, for example, the results of --once twice in 
the same window.


What version of jvmtop are you using? On what operating system?
v0.7.1 on RHEL 6.4

Please post the output of the following commands:
java -version:
java version "1.7.0_25"
OpenJDK Runtime Environment (rhel-2.3.10.4.el6_4-x86_64)
OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)

[jboss@testbox ~]$ echo $JAVA_HOME
/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.25.x86_64


Please provide any additional information below.

A suggestion: --once is a rather limited (imp lice a --twice, --thrice).   An 
argument -n <iterations> might be more flexible.
