Over the years, I've updated my update process to what causes the least
issues, for me at least.  This is what I type in:

eix-sync && emerge -uaDN world

This is the settings I have in make.conf:

EMERGE_DEFAULT_OPTS="--with-bdeps y --backtrack=100 --keep-going -v -j8
--quiet-build=n -1 --unordered-display"

Obviously some may need to be set differently, like the -j8 part, for
your system but some of that helps no matter what system you use.  The
-1 for example keeps the world file clean since you have to put effort
into adding something to it.  One could add it to the world file
directly or use the --select y option.  Either way, nothing gets added
to the world file because you forgot to use the -1 option.  The
backtrack, so far 100 has worked.  If I start to have issues that a
higher number fixes, it will be upped to that number.  Over time, some
things have been removed since they were no longer needed. 

Your mileage may vary but could give you a good starting point.  Took me
years to get to that simple line.  ;-)  If anyone is interested, I could
post some other things from make.conf I've picked up over the years. 

Hope that helps.
