There are several LORs with unionfs reported. One seems to lead to a hard lock. For example I used to mount /usr/local/etc via unionfs over read-only unerlaying ufs. There are reproducably hanging processes with status D+ ofter a short time. This used to work with FreeBSD-7, but also causes problems on -current (see kern/141950) How-To-Repeat: mount_unionfs /somedir/anotherdir /usr/local/etc and try starting lighttpd with php-fastcgi for example. mount_unionfs /somedir /root while / is readonly. Su will hang and force yout to hard reset the machine.
