When smbfs detects that there is something wrong with the connection to
the server (for example that the server has disconnected) it is supposed
to reconnect. I can't say that I know that running programs from smbfs
when it reconnects works, but I think it should ...

When the server drops the connection you should get a message from the
kernel (syslog, dmesg) saying that it did something. The exact message may
vary but something like this:
        smb_trans2_request: result=-9, setting invalid 
        smb_retry: new pid=6783, generation=157 

What samba version and linux kernel version are you using? Some versions
have known problems with reconnecting, you should be using 2.0.7 and
2.2.18-pre25. If you get "smb_retry: caught signal" messages then you are
using a bad version.

It would certainly be possible to add an ioctl or something to be able to
force a reconnect from some userspace program. But again, this should
happen automatically.
