Thanks for everyone's help and thoughts. I agree that this behavior is
buggy. I submitted a bug report to the python project at sourceforge,
with a link to this thread. Hopefully the report will be helpful.

Indeed, looking at sources, the posix version uses the mkstemp/unlink
idiom.. but in win it uses a bit of hackery. It seems opened files
cannot be unlinked.
if _os.name != 'posix' or _os.sys.platform == 'cygwin'

Good thought Chris,
Normal reading and writing does seem to work. ..
But, my friend Daniel figured out a workaround when I asked to confirm
this behavior on his windows setup (and it is does behave the same for
him). The first clue was this:
>>> f = tempfile.TemporaryFile()
>>> type(f)

did you try reading and writing to/from that temp file with regular old
python functions?

fromfile and tofile work fine on regular files. From skimming the code
a bit, it's hard to imagine numpy cod

Hi Chuck,
Thanks for checking that. I am running numpy 1.0.1 in python 2.4 on
win32 (xp). Are you on linux? I double checked the behavior in 1.0
and 1.0.1, just to be extra sure, and it thows the IOError in both cases.
