Automatic/triggered reload in calibre-server?

Hello,

I recently started using calibre-server in daemon mode on my FreeBSD server to share my library among friends and I saw that update to the library is not seen by calibre-server unless I kill/restart it.

Is there a way either to have it reload by itself the books' list or a way (signal SIGHUP/SIGUSR1 or a file) to trigger such reload?

Thanks.
