	Using samba-3.0a20
>Description:
	When mounting a remote filesystem on a windows machine (machine A) using the mount_smbfs command on the FreeBSD machine (machine B),
	and re-exporting this filesystem using the samba suite, machine B will lock up when machine A tries to connect to the exported drive,
	which is in fact it's own share.

	smbd will start consuming a lot of memory for a short while, after which nothing seems to function anymore, not even terminal handlers
>How-To-Repeat:
	1) mount_smbfs //user at remote_server/share /mnt/blah
	2) export /mnt/blah using samba suite. Example of smb.conf:
	[blah]
        path = /mnt/blah
        public = yes
        writeable = yes
        printable = no

	on remote_server mount share blah from FreeBSD server and attempt to access
