Typically the reason for putting temporary files in the current directory
is so that they are created in a JTREG managed directory and cleaned
up as needed. By putting the files in /tmp you will be putting them in
a place where JTREG won't deal with them. Also, in the event of a test
failure, will the file in /tmp be left behind?
