allevents stops updating after trimhistory

Henrik,

On Solaris 9 hobbit 4.1.2 and RedHat 4 hobbit 4.2 I ran trimhistory and
noticed the next day that no events were listed at the bottom of the bb2
page. Working on my 4.2 test system I found hist/allevents stopped
updating after running trimhistory. Restarting hobbit got it working
again. Hobbit should not require any additional restarts after running
trimhistory or it should be mentioned in the man page.

Thanks,
John
