  well, this will explode on many quite reasonnably sized systems. This
should also use a memory-limit that could be auto-guessed from the
system total physical memory (50% of the actual memory could be a good
idea e.g.).

  On very large repositories, using that on the e.g. linux kernel, swaps
like hell on a machine with 1Go of ram, and almost nothing running on it
(less than 200Mo of ram actually used)
