Tracing back objects

Hi,

The following code:
 CompiledMethod allInstances inject: (CompiledMethod allInstances first) into:
[:m :i | i size > m size ifTrue: [i] ifFalse: [m]].

gives the largest method as an object. Is there an efficient way to trace back
the method selector and its class without doing a brute force lookup?

TIA .. Subbu

Note that

        CompiledMethod someInstance

is much more efficient than

        CompiledMethod allInstances first

Not in 3.8, but I think later versions might cache the owner of CMs.  
Anyway, you might want to try this:

(CompiledMethod allInstances detectMax: [:m | m size]) who
