Hi,
I've changed my CFLAGS settings and merged ccache for later works. Now i'm
updating my system with "emerge -e world". During merge i realize that
ccache is adjusting permissions for 4 times per package; before merge,
before unmerge of existing packages, after unmerge and after merge. It's
something like this:

--- !targe sym /usr/lib/libglib-2.0.so <http://2.0.so>
* Adjusting permissions on ccache in /root/.ccache
>>> original instance of package unmerged safely.
* Adjusting permissions on ccache in /root/.ccache
>>> Regenerating /etc/ld.so.cache...
>>> dev-libs/glib-2.6.5 merged.
* Adjusting permissions on ccache in /root/.ccache

>>> clean: No packages selected for removal.

>>> emerge (133 of 405) x11-libs/pango-1.8.1-r1 to /
* Adjusting permissions on ccache in /root/.ccache

My question is about this adjusting process, each adjusting process longs
about 5 to 6 seconds. For whole update this makes 135 to 162 minutes and if
this really is only an permission adjusting process i thought this is just
loosing time. Can you help to understand this and if there is a setting for
this that i've missed would you show me?
