Hi,

I had been happily running 5.0.9, then suddenly this "Variable binding
depth exceeds max-specpdl-size" error appeared at Gnus startup.  I
fetched 5.0.12 to check if this still happened with the latest
version, and it did.

Further investigation (starting up tin (ugh!)) gave the response

vo5>gnus-5.0.12 62 % tin -r
tin 1.2 PL2 [UNIX] (c) Copyright 1991-93 Iain Lea.
Connecting to news.liverpool.ac.uk...Connection to news server has timed out. Reconnect? (y/n): y

so apparently,  there is a problem with the news server connection
which is handled gracefully by tin,  but.. erm... slightly
ungracefully by Gnus 5.0.12 

[Backtrace follows ... actually from the 5.0.9 crash,  but I can't
imagine it being different in the 5.0.12 crash.]

What's going on here, ... what is making Gnus repeatedly open and
close the server?
