I have similar trouble using nnimap with openssl and starttls on
Cygwin. There seems to be some problem with how Gnus or XEmacs detects
that a connection dropped.

Sometimes when I go to check for new messages in an nnimap group, I'll
try, say, "1-g" to check groups at level one. That will hang, so I'll
hit C-g to cancel (sometimes it takes many tries), then place my
cursor on the group in question and hit M-g. That /sometimes/ checks
the messages again with the same dropped or corrupted connection, so I
have to stop Gnus again, go to the Server buffer, and try to close the
supposedly open connection there. Of course, trying to close the
connection makes Gnus hang again, so several more M-g attempts may
finally yield Gnus recognizing that it has no open connection to this
server. Only at that point can I tell Gnus to open a fresh connection
to check if I have any new messages. This whole process usually takes
close to a minute and around 50 keystrokes.

I don't notice the same problems, at least to the same degree, with
direct connections to the IMAP servers. It's those programs in between
Gnus and the IMAP servers such as openssl and starttls that aggravate
these flaky connection problems.

Even worse is trying to quit Gnus. I notice that for around the last
year of keeping up to date with CVS, Gnus does not quit cleanly if any
of its open connections had dropped. I have to manually kill some or
all of the openssl and starttls processes, as well as hit C-g many
times, to get Gnus to shut down. I can't tell if this problem is
directly related to nnimap or not.
