always use rk_getpwnam_r...
--
This is why we have libroken...
--
Use getpwuid_r instead of getpwuid, so that we don't trash getpw*() internal
buffers.
kde does (kdm/client/backend.c):
p = getpwnam();
pam_setcred() (which calls getpwuid in pam_afslog);
setusercontext(...,p,p->pw_uid,...) (now with trashed p data...)
