New description:
This was detected in the following speed regression
In vanilla sage 4.6.2
{{{
sage: a=Integer(1000)
sage: b=int(1000)
sage: c=[0]
sage: %timeit c*a
625 loops, best of 3: 21.2 µs per loop
sage: %timeit c*b
625 loops, best of 3: 5.21 µs per loop
}}}
In vanilla sage 4.7.rc4
{{{
sage: a=Integer(1000)
sage: b=int(1000)
sage: c=[0]
sage: %timeit c*a
625 loops, best of 3: 568 µs per loop
sage: %timeit c*b
625 loops, best of 3: 5.13 µs per loop
}}}
By default the coercion model should not be recording exceptions ocurred
in the execution of sage unless explicitely anabling reconding exceptions
for debugging support.

Comment(by lftabera):
No, this code is stull valid. The speed regression is gone, but the
functions that control the record of the exceptions is still valid and
worthy to include in sage.
