the tail file of course. Called from TBdbfork() in libdb, EventFork
resets the event handle so that the child does a reconnect. Note that
I do not disconnect in the child since I have no idea what that is
going to do to the parents connection to the elvind, as Elvin makes no
mention of what to do in the presence of a process that forks after
connecting to the event server. At the least, this avoids a bunch of
warnings and errors from vnodesetup!
