The following works on cpython, but fails on pypy:

a.flags.writeable = False
E TypeError: readonly attribute
So I went and installed pypy's fork of numpy from source, and tried to
start poking around looking for tests, etc. to see what was going on.
It looks like numpy/core/tests/test_multiarray.py
TestFlags.test_writeable is doing something similar, but when I
attempt to run the tests like so:
pypy -c "import numpy; numpy.test()"
(Is that the right way to do it?)

Thanks for looking into this. It seems there are two seperate issues,
the failure to set flag attributes and the failure to run tests.
Could you give a few more details about how to reproduce the second
problem: which pypy and how did you obtain it, and how you
built/installed numpy into it? What imports did you have to change?
You shouldn't have to change imports, but it is entirely possible that
we have overlooked something.
