Oh, yeah.. the problem was that DNS timeouts took too long. It looks as
though this has already been addressed in /etc/resolv.conf:
options Allows certain internal resolver variables to be modified. The
options option ...
where option is one of the following:
sets the amount of time the resolver will wait for a
response from a remote name server before retrying the
query via a different name server. Measured in sec
onds, the default is RES_TIMEOUT (see <resolv.h> ).
sets the number of times the resolver will send a
query to its name servers before giving up and return
ing an error to the calling application. The default
is RES_DFLRETRY (see <resolv.h> ).
