Allowing multiple versions to co-reside and not trash each
other's result would be useful. Presently I need redefine
CCACHE_DIR for each version to avoid overlap, which is
annoying. (On a large multi-os cluster it often isn't possible
to roll out a new version simultaneously.)
Although... if the stats format changes overlap must still
be avoided. Including the version number in the stats
filename would solve that too.
