Exceptions in UploadHandler cause hang

* milestone: => 1.0
Comment:
Further investigation shows the write is not hanging, it is raising an
exception. If I change the code to:
{{{
def write(self, s):
print 'in TemporaryFile(nt), about to call self.file.write(s)'
try:
x = self.file.write(s)
except Exception, e:
print 'Caught exception on self.file.write(s): %s' %
str(e)
raise
print 'in TemporaryFile(nt), back from self.file.write(s)'
return x
}}}
and try to upload to a disk with not enough free space, I see:
{{{
in TemporaryFile(nt), about to call self.file.write(s)
Caught exception on self.file.write(s): [Errno 28] No space left on device
}}}
in my dev server console output. No error is reflected anywhere I can
see, there is no further console output and the browser page that
initiated the upload is stuck at "Loading....".
Changing milestone to 1.0 since this appears to be a more far-reaching
problem than I initially thought and someone should probably take a look
at it sooner rather than later.
Also exceptions in upload handlers causing requests to hang has been
reported here: http://groups.google.com/group/django-
