I located bug #578139 in the upstream at gnome.org that appears to also be this issue. I reported on it the findings here and gave them this bug number just incase.

I did some network traffic logging between gvfs and cifs as any samba mounts via cifs never time out. I discovered that CIFS periodicly sends an SMB Echo Request packet to keep the socket connection open while GVFS fails to do this. As a result a file server may kill the inactive connection however the mount inside of the file browser stays around. As a result, attempts to access the disconnected share results in waiting for an error box to pop up just so it can be unmounted and remounted.
