wd1e uses buffer cache, which has more overhead. rwd1e goes directly to
disk. For fsck and similar tools, /dev/r* is normally used.

One could speculate that the overhead is a bit too serious and that your
experience with -current could show that it was a bug which has been
fixed. But it is only a speculation...

Could you try to repeat with 3.0_BETA or -current more systematically, to
have an useful comparison with 2.0.2 ?
