2.6.8 breaks pop3, telnet

2.
hallo,

on a number of systems that I upgraded from 2.6.6 and 2.6.7 to 2.6.8, mozilla
can no longer access my pop3 mail account, neither can I when using telnet:

telnet pop3.skynet.be 110
Trying 195.238.3.116...
Connected to pop3pool1.skynet.be.
Escape character is '^]'.
+OK Skynet POP3 Ready pop3pool1.skynet.be
user XXXXXX
+OK USER XXXXXX set
pass YYYYYY
+OK You are so in
UIDL
+OK uidl command accepted.


and the connection hangs until I interrupt it. Same thing when I try this from
tcl/tk (wish). strace shows it hangs on recv on Redhat, on a Debian system it
showed select.

patch-2.6.8-rc2 is +3Mb zipped, so if anyone would know where to start looking,
much appreciated!

3.
2.6.8-rc2, telnet, pop3, recv(), select()

4.
2.6.7 : OK
2.6.8-rc2 : broken, I am quite sure the same goes for 2.6.8-rc1

6.
see above
