On my 600MHz machine and GCC 3.3, it takes six seconds to create the
cache for HttT (it would be even faster if I was not using a
zip-install Wesnoth). This it is the delay for the "loading scenario"
to appear after "no valid cache found" was displayed. Once the cache
is built, this step takes less than one second.

And then, it takes ages to display HttT map (the time necessary to
initialize the scenario): 12 seconds. This is huge, it also appeared
at the time of 0.9.0, and the main problem lies within: 
(--log-info=all)

        BEGIN: terrain_builder::parse_config
        END: terrain_builder::parse_config (took 10387ms)

and there is no stream at all in the related functions!

So before discussing the stream matter any further, I would like to be
sure that the many minutes the users experience with the VC6 build are
really during preprocessing / tokenizing / parsing.
