VFS and signals

[Brad Sahr]

It might be handy for the VFS to be notified when smbd receives a signal.
For example, if smbd segmentation faults, this might give the VFS the
opportunity to do some cleanup prior to the process going away. It might
also be handy for the VFS to reread any configuration files when a SIGHUP is
received, as smbd does now.

Is there another way to achieve the same functionality? I'm suspecting that
a process only gets a single signal handler.
