windows checkpointing thrashes because they explicitly turn off caching
and writes after each device tested for. that's a lot of devices, and
it's very quick to test for each -- quicker than it is to write the
checkpoint info. but they decided it's worth it in order to have
bulletproof autodetection. it's not, imho.
