It's only supposed to be doing this for the first cygwin process that
start up on a given console. Is that, again, no longer the case? It
seems like we keep drifting here. We shouldn't be incurring the
/etc/group and /etc/passwd startup costs even when ntsec isn't
Anyway, I'll take a look at your patch later today, Pierre.
