Summary: test_b1.py, disabling of list test

Initial Comment:
Guido disabled the list(xrange(sys.maxint / 4)) test
for 64-bit machines because PySequence_Length returns
an int and not ssize_t.

The test needs not be disabled; for the time being, it
should be
list(xrange(min(sys.maxint / 4, 0x1fffffff)))

There is another flaw, btw.
I ran the test on a 512MB RAM 64bit machine, and it passed.
However, when I ran it on a 16GB RAM 64bit machine, it
raised TestFailed incorrectly(!), because the statement
did not produce a MemoryError...  I think this is
probably the only occasion the 'else' part was ever
evaluated (but ICBW :) 

I did not supply a patch, because I didn't want to mess
with Guido's comments.  

<HUMOUR>
Perhaps the test should be just:
try:
    list(xrange(min(sys.maxint / 4, 0x1fffffff)
except MemoryError:
    pass
else:
    print "I wish this passed in my home machine too..."
</HUMOUR>

I did indent the humourous code above, but the indentation
got lost after posting.  Just in case the code was actually
used... :)
