Segfault handling for preexec

[Jan Engelhardt]

Hello list,



I once had the case where my preexec script/program segfaulted and logins were 
refused. So here is yet another patch to allow logins if the preexec script 
was killed. Once again, opinions please.

(Do not spend attention to the version numbers in the patch..., works with 
3.0.9 too)
