Update the comment and remove the close. If we close we can't flush anymore.
We might still need to close after the for loop if flushing 6! times still
doesn't cause the signal/exception.

Try to handle socket.errors properly in is_unavailable
........
r60370 | christian.heimes | 2008-01-27 20:01:45 +0100 (Sun, 27 Jan 2008) | 1 line
Change isbasestring function as discussed on the cvs list a while ago
........
r60372 | neal.norwitz | 2008-01-27 21:03:13 +0100 (Sun, 27 Jan 2008) | 3 lines
socket.error doesn't have a headers attribute like ProtocolError.
Handle that situation where we catch socket.errors.
........
r60375 | georg.brandl | 2008-01-27 21:25:12 +0100 (Sun, 27 Jan 2008) | 2 lines
Add refcounting extension to build config.
........
r60377 | jeffrey.yasskin | 2008-01-28 00:08:46 +0100 (Mon, 28 Jan 2008) | 6 lines
Moved Rational._binary_float_to_ratio() to float.as_integer_ratio() because
it's useful outside of rational numbers.
This is my first C code that had to do anything significant. Please be more
careful when looking over it.
........
r60378 | christian.heimes | 2008-01-28 00:34:59 +0100 (Mon, 28 Jan 2008) | 1 line
Added clear cache methods to clear the internal type lookup cache for ref leak test runs.
