gnutls problems again

[Lars Magne Ingebrigtsen <larsi@gnus.org>]

The Gmail IMAP servers seem to be having problems again, but it triggers
an interesting gnutls-related bug.

If I say:

(gnus-open-server '(nnimap "imap.gmail.com"))

then Emacs starts using 100% CPU.  Emacs doesn't hang, but as long as
that connection is up (i.e., until I kill the process buffer), then
strace says the following:

poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}], 2, 0) = 0 (Timeout)
select(10, [3 4 6 7 8], [], NULL, {0, 0}) = 1 (in [8], left {0, 0})
getrusage(RUSAGE_SELF, {ru_utime={44, 494780}, ru_stime={8, 100506}, ...}) = 0
times({tms_utime=4449, tms_stime=810, tms_cutime=0, tms_cstime=0}) = 1731291756
getrusage(RUSAGE_SELF, {ru_utime={44, 494780}, ru_stime={8, 100506}, ...}) = 0
times({tms_utime=4449, tms_stime=810, tms_cutime=0, tms_cstime=0}) = 1731291756
read(3, 0x11fe4f4, 4096)                = -1 EAGAIN (Resource temporarily unavailable)
poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}], 2, 0) = 0 (Timeout)
select(10, [3 4 6 7 8], [], NULL, {0, 0}) = 1 (in [8], left {0, 0})
getrusage(RUSAGE_SELF, {ru_utime={44, 494780}, ru_stime={8, 100506}, ...}) = 0
times({tms_utime=4449, tms_stime=810, tms_cutime=0, tms_cstime=0}) = 1731291756

And a *lot* of that.
