Thanks for the bug report!

Is ccache busy consuming CPU cycles or is it idle?

It would be helpful if you could make a copy of
38b5811e7e57c1e0c2518697ad6c91-427760.manifest available and also run
strace on the command that hangs and post the results, i.e. the output
of "strace ccache /usr/obj/src/tmp/usr/bin/cc [arguments...]".
