Well spotted. Prior to the CR 6721753[1] fix File.getTempDir hand-coded 
lazy initialisation of tmpdir. It shouldn't make an enormous amount of 
difference: updates to the system property currently change the temp 
directory used; the performance degredation should be trivial.

I guess Alan will sort it.
