Summary: test_builtin memory error strangeness

Initial Comment:

Don't understand what's going on here. One of the tests in test_builtin deliberately provokes an out of memory error by executing: 

 list(xrange(sys.maxint // 2))

and the test is successful when the resulting MemoryError is caught. This works fine when running the test stand-alone or with regrtest with no options. However, when running regrtest -a the test fails with a java.lang.OutOfMemoryError being raised, ie it doesn't match the MemoryError in the except cause and so isn't caught.

Curiously, simply adding the statement:

 import java.lang.OutOfMemoryError

to the top of test_b1.py causes the test to succeed again even under regrtest -a.  

Observed on trunk with jdk 1.4 & 1.5 on linux.

I was looking at this last night too after seeing it in the 1.4 Windows
buildslave.  I can't get it to happen under 1.4 or 1.5 on the Mac, or 1.5
or 6 under Windows.  It I cut regrtest.py down to running just test___all__
and then test_builtin it fails, but not with just test_builtin even from
within regrtest.py.
