i'm looking into a problem with gaim 1.5 + gnutls 1.0.25 where 
disconnecting from a jabber server with TLS supprt (wildfire, in this 
case) causes gaim to hang. here's the backtrace of the hung process:

i'm not sure whether the problem is on the client side or the server (e.g. 
is the server not replying to our request to close the connection?), but 
i'm hoping for some pointers in the right direction. if, indeed, the 
server isn't sending a reply, is there a way to set a timeout so the 
client won't wait forever for a reply that isnt' coming?

from the application side, i guess i could grab the transport ptr and set 
a timeout on the socket before calling gnutls_bye. does that sound
