pardon my ignorance wrt dynamic-wind and call/cc, but does that^ mean
that 1) i should simply leave the wind part of the dynamic-wind empty
and move back the open-connection call into the let... or that 2) the
entire idea of replacing the exception handler with an unwind-protect
is flawed?

if 2) then i'll try to smarten up the handler to use raise-continuable
if the exception is of type &warning.

or any better ideas?
