This patch attempts to provide users with support for
enabling the timeout feature on the undlying socket.

new parameter added to the __init__ and connect().

i have tested this only briefly.

ftp = ftplib.FTP()
ftp.connect(host="ftp.python.org", timeout=2)
ftp.settimeout(0.01)
->  Error socket.error: (11, 'Resource temporarily
unavailable')
ftp.settimeout(1.2)
ftp.login("anonymous")

There's no uploaded file!  You have to check the
checkbox labeled "Check to Upload & Attach File"
when you upload a file. In addition, even if you
*did* check this checkbox, a bug in SourceForge
prevents attaching a file when *creating* an issue.

Please try again.

(This is a SourceForge annoyance that we can do
nothing about. :-( )

The patch i suggested could be applied at a higher level of
abstraction to counter duplication in other connect()'s in
most other Protocols.

Please consider the following argument  (on google):

The classes ftplib.FTP, telnet.Telnet,
httplib.HTTPConnection are affected. There may be more (?)
NB open function is more or less the same as connect in
telnetlib.
