Profiling tools (is gprof+"recompile the world" all there is? why doesn't everyone have pixie!) didn't reveal much, but top shows that lookupd is burning lots of cycles. Apparently we're doing lots of lookups (of passwd entries I guess) that the native version doesn't do? Under linux the difference is very much less, but it's there. At first I attributed it to something minor like bio doing less buffering than stdio, but maybe that's not the whole story.
