test_buffered_reader test_gzip is failing for me since r80720, on trunk on OS X
10.6.3:
======================================================================
ERROR: test_buffered_reader (__main__.TestGzip)

IOError: [Errno 9] Bad file descriptor
Here's a minimal Python script that produces the failure:
import gzip
import io
f = gzip.GzipFile('hamster', 'wb')
f.write("some data")
f.close()
f = gzip.GzipFile('hamster', 'rb')
r = io.BufferedReader(f)
lines = [line for line in r]
r.close()
This gives the following output:
Traceback (most recent call last):
File "test_gzip.py", line 11, in <module>
r.close()
File "/Users/dickinsm/python/svn/trunk/Lib/gzip.py", line 365, in flush
self.fileobj.flush()
