With the latest CVS changes in libresolv (also included in FC10),
res_state.nscount is not always initialized to 1 anymore. However,
__res_maybe_init() code will reinitialize the state only if nscount is > 0 for
unknown reasons - I think it is just an oversight in the original code. Attached
patch proposes to fix it.
This exhibits in random resolution failures if nscd is started before
/etc/resolv.conf has been set up - I did not go through the code in detail but I
assume the existing threads will never get the new res state because nscount ==
0 in their original state.
