Looking at the relevant *Acquisition.c files, both implementations of 
aq_inContextOf(2.7.6 & 2.8.0b2) are identical.  The implementation of 
macros used in this method (isWrapper, WRAPPER, and OBJECT) are also 
identitcal, there being nothing else immediately  obvious that looks 
like it could have been implemented differently there.

I would hence suspect the wrapping, and/or behaviour of the object 
and/or context to be somehow different?
