Question: the user+host as listed on PROCESSLIST do not necessarily reflect any 
GRANTEE account. 

Compare this to USER() and CURRENT_USER().
The processlist identifies the USER() while the grantee refers to 
CURRENT_USER().

How do you solve that?

Hrm, currently I don't have a way to solve this.  I think it would require some 
changes to the server to report CURRENT_USER in another column of processlist.

A solution is presented here:

I've already committed the function code; not yet released
