I won't test it myself (I stopped playing guinea pig quite a while ago),
but I think - as I already said - that a default of 2048 is way too low.

This patch tries to "fix" a problem which does not exist for such small
numbers of files. The potential problems it may introduce are however
now inflicted on many users - due to the small default. On a platform,
which is already shaky enough (Windows).
