fsck_ffs -E -d /dev/mirror/gm0 on fs with 390gb data after gmirror rebuild

This test was done on following way:

FS (mounted on /mnt) contained 200G of data.
gmirror remove gm0 ada1
gmirror insert gm0 ada1
dd if=3D/dev/zero of=3D/mnt/1.tst bs=3D10m count=3D102400
On another terminal i run systat -vmstat.
After few minutes ada1 become 99% busy (ada0 was busy at 33%), MB/s lowered
from 255 Mb/s (sata2 controller used on this machine) to 85 MB/s.

dd was stopped when file /mnt/1.tst reached 190G size.

And finally
umount /mnt
fsck_ffs -E -d /dev/mirror/gm0

I could not reproduce the problem when fsck_ufs run more than 6 minutes.
