repalce cinnamon (when it springs a memory leak)

cinnamon-replace

#!/usr/bin/env bash
#
# This script may be used when cinnamon springs
# a memory leak. Running this script will start 
# a screen session and run 'cinnamon --replace'
# within this new session.
#
# Presently, this is a script to be run manually.
# perhaps in the future a deamon to keep an eye
# on memory usage would be a good idea.
#
# There is already a feature within cinnamon which 
# is designed do this kind of auto reloading  should 
# the specified momemry limit be exceeded. However, 
# I have not had this work reliably and hence 
# the creation of this script to manually spin 
# a new instance up as required.
#
# Hopefully, in a future version of cinnamon, this 
# script will become obsolete.
#
# You may need to tweek your display settings to
# ensure this works for your configuration.
