ever since moving to ldap for passwd/group/shadow/hosts lookup, ping to a non-reachable host just freezes up and never returns:

Try ping -n. This is most likely something else.
hmm. ping -n would still have to look up the hostname, and indeed the strace is identical (hanging). but when i ping the ip (this is probably what you had in mind), it works as expected.
anyway, why would a process block endlessly in a futex?
