Well, this is really a hardware limitation. User cannot monitor more events on a 
package than # of RMIDs at the *same time*. The 10/14 reuses the RMIDs that are 
not monitored anymore. User can monitor more events once he stops monitoring 

So we throw error at the read (LAZY mode) or open(NOLAZY mode) ..
