Temp directory filling up, causing failure

[xEtherealx]

Running 3.4.2 via pip on Centos 6.4, python 2.6. The temp directory (/tmp) is 10Gb on my system and is filling up during a call to 'blueprint-create test' causing failure. A switch allowing the user to define the temporary working path would be good. In the meantime, is there a workaround for this?

I do have ignores set up in /etc/blueprintignore but they aren't sufficient to trim the size below my temp partition size.
