the CM is going to send the UP probe to every server the client has ever 
communicated with once the 5 minute check comes around so there is no 
point putting it off.  Just make sure that you reset the 5 minute check 
timer when you do it.

Updating the UNIX CM to use multi_VL_ProbeServer instead of
probing each VL server in serial would be a win.
