I agree the contrast isn't entierly real.  I just switched the default
back because the scripts we had were forcing textdumps.  What I'm
thinking of doing is removing the textdump part of the default script
and adding some code to let you set the dump type with an easy rc.conf
variable.  Then turning the script back on.  Hopefully someone(tm) will
add the code to extract textdump data from minidumps so we can have the
best of both worlds.
