bug#17845: Still happens with Emacs 24.4

[Rainer Orth]

I'm also seeing this issue on Solaris 11/x86 (i386-pc-solaris2.11): on
my workstation, it occured for the first time when switching from Emacs
24.3 to 24.4.  With a 100 Mbit/s connection to the IMAP server,
gnus/nnimap is barely usable.

The issue isn't new, though: on my Solaris 11/x86 laptop, it occured for
the first time when switching from Emacs 23.3 to 24.1, and in all
versions up to and including 24.4.  With slower network connectivity,
the Emacs 24 versions are completely unusable due to this bug, so I have
to stay at 23.3 there.

Any suggestions on how to further investigate this?  This bug is most
annoying.

Thanks.

        Rainer
