It sounds like he downloaded distfiles before checking.

Do you mean 1022k blocks to give 1GiB?  Since each block is normally
1KiB...

One hypothesis would be that if you are running KDE while doing the
upgrade, then the kernel can't immediately overwrite some of the 4.8.0
files with 4.8.1, because if you're still running the old 4.8.0
binaries, libraries, etc. in memory, they are kept around on disk
until the processes using them finish (though during that time, all
accesses to those filenames will reach the new versions).  Once you
log out / reboot, this old space will be reclaimed.  I'm not sure how
much this affects something like KDE that relies heavily on shared
libraries.  Of course if the space stays used then it's some other
cause entirely.

Also, this is tangental to your problem, but don't forget about
"eclean-dist -d -f" if you want to clean up old distfiles :).
