  here's what seems to be a pattern.  fetching mail will work just
fine after i've set up my laptop on someone's network.  when i shut
down and move to someone else's network (say, dropping by to visit
someone and latching onto their home wireless), there's a non-zero
chance that fetching mail will now have that horrid time lag between
fetches, *unless* i simply restart the system.  then, chances are
everything is just fine.

  it's as if the *first* boot at the new location still has some
vestige of the previous location's DNS info, but doing a *second* boot
finally clears it out.

  does that make even minimal sense?
