However, that still leaves unexplained why
SCNetworkCheckReachabilityByName was reporting the address
unreachable where a http request for that same address was instant.
Could it be that there are still some remaining network issues with
10.3.8 for which some APIs are vulnerable and others not?
When you connect, how are you resolving the name? There are many
different ways to resolve DNS names on Mac OS X. Most, but not all,
are routed through to lookupd. If lookupd is dead (or sick), this
could explain the delay in calling
SCNetworkCheckReachabilityByAddress.
