yes, but for a Really Really Big (TM) application, 100ms additional load
time is something like statistical noise. ;)
i'm way more concerned about the tiny applications that somebody might
want to use in scripts. we already discarded the idea of using
kreadconfig in startkde, because it's just too slow. at least it was
before the core/ui split.
fwiw, there is another factor that was not considered yet: bootup load
penalty, i.e., with cold disk caches. then the 4ms easiliy become 400ms,
and this adds up quickly. one notable difference to the above used
per-app calculation is, that this matters only once for every depedency,
so the total number of deps counts, not how many apps use them.
