After a lot of headaches over some mysterious behaviour in some
scripts, I found the following:
I have two files:
test1.sage contains:
attach test2.sage
print "test1", 1/2
test2.sage contains:
print "test2", 1/2
When I say on the command line of sage 3.3: attach test1.sage, the
output is (correctly):
sage: attach test1.sage
test2 1/2
test1 1/2
But on sage 4.01, the output is:
sage: attach test1.sage
test2 0
test1 1/2
It looks as if on a file that is attached from another attached file,
no preparsing takes place. If within this same session I touch
test2.sage, it works fine.

It looks like this is a problem with the IPython interpreter's "attach".
This is now
