I can't reproduce it, i remount the filesystems

at will? if yes, could
you say exactly how are you doing it?
Interesting - when i umount fs i'm able to mount it rw. I can't
remount rw mounted partition. Try this:
Mount /a ro on boot, i mean set read-only in fstab
Same with /a/b and /a/c.
Try to remount /a/b rw with mount -rw /a/b.
No processes in /a/b, no open files.
And, that's strange - / is ro on boot, i can remount it rw without problems.
All FS are UFS with soft-updates.
