Summary: Core dump when using mmap.

Initial Comment:
Ok, it is dumb to read from a file before it is written
to.  But, via mmap I did it by accident and it dumped
core.  Here is a simple linux example which will do it.

d0lxac1% touch dummy
d0lxac1% python
Python 2.1 (#3, May 16 2001, 15:15:15)
[GCC 2.95.2 19991024 (release)] on linux2
Type "copyright", "credits" or "license" for more
information.
>>> import os,mmap
>>> x = os.open('dummy',os.O_RDWR)
>>> m = mmap.mmap(x,4700)
>>> m.read(47)
Bus error (core dumped)
d0lxac1%

Yeah, its dumb, but should it really dump core?

Thanks.
