Two observations:
1) I'd put the output of the spam command to an intermediate file instead of 
an environment variable. Doing so might not be quite as fast, but it would 
not be resource constrained.
2) $PWD is a standard environment variable, so you should use some other 
name to save your previous PWD value, e.g.
PREVDIR=$PWD  # or PREVDIR=`/bin/pwd` - same result
do your stuff
cd $PREVDIR

cd $PWD
would be the same as
cd `/bin/pwd`
