Actually file could be downloaded and uncompressed without using /tmp at all. 
Simple shell script example:

wget "$URL" -O - | gunzip | tar xf - 

I think this is right approach. Most likely knewstuff wasn't designed with 
really big files in mind.

Right component is knewstuff in kdelibs. And please post bug number here if you 
report this issue.

P.S. Currently KStars uses old knewstuff2. I will port it to new variant 
shortly.
