I don't have the original report, so I don't know under which circumstances the hang happens there. In my case it happens if I connect to the internet via modem, open an encrypted connection to an IMAP server, cut the internet connection, connect to the internet again, and try to connect to the IMAP server again. I am not sure if this is a problem of Emacs, the programs used for opening the connection to the server, or the kernel. I tried it now with openssl s_client, starttls, and gnutls-cli. All three behave identically on GNU/Linux, i.e. the hang happens with all of them. BTW, in contrast to Emacs on GNU/Linux, the Windows port of Emacs does not hang. Perhaps this information helps identifying the cause. -- Ralf
