Hi,
> What is this tmp directory?
ccache's tmp directory is used to store temporary preprocessed source code.
Files should normally not be left in tmp, but if ccache exits unexpectedly
(if it crashes or is killed) then files may be left there. Looks like this
has happened to you a lot.

No other reason than that nobody has implemented such cleanup code. :-)
I'll see what I can do.
