:)  Sweet.

Yet, binary distros are riddled with bugs, and are much more annoying to
fix given the the cumbersome edit/build package/install package cycle.

Heh, because compiling code magically makes the bugs go away.  Wow, I
never knew that....

Honestly I find even that hard to believe;  unused pages can be swapped
out.  And once shared libraries are memory-mapped additional references
are essentially free.  So unless the architecture has a totally crap I/O
subsystem (so load times are horrible) or a very decrepit MMU - a
perceptible change is hard to believe.

yep.

In the interest of full discloser this snickering-at-Gentoo message is
being written by a guy [me] who owns a 1919 Model-T Ford with a
high-lift camshaft, alloy pistons, a SCAT racing crankshaft, kevlar
transmission bands, and a Bosch ignition system.

Note that a Model-T Depot Hack weighs next to nothing - so
out-of-the-gate I can "smoke" just about anybody.
