It can't be done without modifying Tk. But if I do modify Tk in a way that 
puts the results in variables, then I can pick up the results in Tcl and 
send them back to Pd, so that, in addition to [cputime] which measures 
only server time, you'd have a few more measurements, such as total time 
spent in Tcl/Tk, total time spent in the Tk part, total time spend in the 
rendering part of the Tk part, total time spent parsing, etc.
