with Gentoo, we've often seen unexpected reboots (power loss / oom /
oops / etc...) result in zero byte files being left in the cache.
comes up semi-frequently for us since so many people are using ccache
and building from source.  the zero byte aspect makes sense when using
ext4 due to the fs design (metadata gets committed, but contents are
in transit and lost).

perhaps ccache itself should grow a 0 byte file check.  i cant imagine
any valid compiled object being 0 bytes ...
