Rebooting an IOC

[SAA@SLAC.Stanford.EDU]

Hello,

I'd like to add a "reboot" button for each IOC on one of my 
lower-level, system EPICS displays.  My first thought was to have
the button initiate processing of a subroutine record that simply 
calls reboot().  But I'd like the reboot to happen when the IOC
is "quiet", in particular, when there are no files being written
by the save-restore tasks (the tasks that save user-enterable channels 
that need to be restored during bootup time for a bumpless reboot).  
Now, I realize that this is a luxury I don't get when the IOC crashes 
or when somebody powers the crate down but, happily, these events don't
happen very often.  

Does anybody have anything they can share on this subject before I go
too far down this road?  Advice, comments, code?  Thanks very much,
