No. "kill" in question is cygwin kill, which NTEmacs doesn't know
about. NTEmacs is a windows process, so only knows how to send windows
process signals. As far as I know, windows doesn't do SIGALRM -- I
could be wrong. I try not to get this close to the OS where ever

No, I don't think you are right. From the Gnus/imap documentation.

So, I am using OpenSSL not tls, nor gnutls-cli to communicate with my
IMAP server. The communication layer works fine here. Certainly, my
imap connections worked fine without gnutls-cli being installed.
