+- Issue #9136: Fix 'dictionary changed size during iteration'
+ RuntimeError produced when profiling the decimal module. This was
+ due to a dangerous iteration over 'locals()' in Context.__init__.
+
- Fix extreme speed issue in Decimal.pow when the base is an exact
power of 10 and the exponent is tiny (for example,
Decimal(10) ** Decimal('1e-999999999')).
