Build /tmp output garbage

Hello guys,

I have running tinderbox instance and i noticed that TMP is continuously
spammed with various tmp files provided while libreoffice build was run.

After a week of run it amounts to 150 mb of data.

Sample files:
-rw-------  1 scarabeus scarabeus 3,9K 28. kvě 00.31 lu88dbjh.tmp
-rw-------  1 scarabeus scarabeus 3,8K 28. kvě 00.31 lu88dbj1.tmp
-rw-------  1 scarabeus scarabeus    0 28. kvě 00.31 lu88dbkf.tmp
-rw-------  1 scarabeus scarabeus    0 28. kvě 00.31 lu88dblp.tmp
-rw-------  1 scarabeus scarabeus 4,7K 28. kvě 00.31 lu88dbl9.tmp

Is there actually some plan to make libreoffice build cleanup after itself
(even with crashed build these should be gone).
It is not such problem for me as I reboot once every few months so this
gets wiped from tmpfs, but still it should not happen.

Cheers

Tom
