[issue12029] Catching virtual subclasses in except clauses

[Georg Brandl]

Georg Brandl added the comment:

Quick microbenchmark:

try:
    {}["a"]                       
except KeyError:
    pass

original tip:  1.35 usec
with patch v3: 1.55 usec

so it's about 15% slowdown for catching a simple exception on my machine.
