This does not occur in the current release of MacOSX. Apple even
mentioned in the update to 10.3.7 that the release fixed this
problem. Upgrade. FWIW, the problem seems to have been in Apple's
resolver library (or equivalent), not Safari. Other browsers had
similar behaviour until the OS was updated.
